Crosh shell not opening - illegal Instruction (core dumped) #1362
Comments
|
Best I can think of is that Brunch is sending illegal(unsupported) instructions to your CPU. What exactly is your CPU model? Maybe try a different recovery image, "syndra" or "syndra" might work? - FYI I'm not sebanc, and it could be something else |
|
I meant "syndra" or "caroline" - just to try :) |
Processor: Intel(R) Celeron(R) CPU B820 @ 1.70GHz |
|
That's Sandy Bridge. There shouldn't be problems with Sandy Bridge, but a "fairly recent" Celeron is recommended. You could try "nami" recovery image, or use "caroline" (try caroline first). It may just be that the rammus image is using unsupported instruction sets. Try these two and get back to me if they don;'t work :) |
Is "nami" image supported by Google and my CPU? |
|
Yes, the “nami” image is supported until 2025 (rammus hits EOL in 2026 - a year after nami) but nami should have better support for your CPU. This is an honestly weird error, and usually, these weird errors on seemingly supported CPUs (this is the actual Sandy Bridge architecture) can be solved using a different recovery. |
|
FYI, the Brunch page says that Baytrail or later is needed - you have the older "Sandy Bridge". You could try a different recovery ("nami" or "caroline") and if they don’t work, you could try "samus" (if you're OK with a release of Chrome OS from June 2021) - that has a higher chance, but is now end of life - sorry for the confusion with this comment |
On stable and beta version, crosh problem is resolved but in dev - the problem is the same. Maybe, if I change the kernel in the brunch settings for booting this image - i can use crosh on the dev version too. |
|
Ohhhh… you are on ChromeOS Dev builds. You usually need brunch-unstable to use dev builds (it contains the latest Brunch code). Do you have the Brunch PWA installed on your Brunch laptop? |
|
That’s how you change from brunch-stable to brunch-unstable(brunch dev releases) |
I'm using Brunch Unstable (the latest version for Unstable builds) Brunch PWA is installed (Now on kernel 5.15 - dev channel and crosh works but when I choose to boot to the Brunch settings, my device is booting to the chrome os normally. When I choose to boot Chrome OS normally, doesn't boot at all - can't find chromeos.img - can't mount /dev/sda7: no such device) |
|
Maybe a messed up grub config. Press E on the Brunch option and see what is going on. Tell me what shows up in the grub editor. |
Fixed. When I changed brunch kernel from 5.15 to 5.10, it's working now normally |
|
Great thanks! |
|
I'm too having the same problem crosh closes as soon as i press Ctrl+Alt+T. |
|
@admin-elvistrujanovic Can please help me how u solved this issue |
|
Don't use kernel 5.15 |
|
I'm using kernel 5.4 only still |
|
@admin-elvistrujanovic I'm using kernel 5.4 only still |
|
What is your computer?

DDR2 on a laptop that was only compatible with DDR3? This laptop should work with Rammus, and it seems that your hardware is similar to of @admin-elvistrujanovic. (You both have 2nd gen Intel CPUs wi5 HD3000 graphics) FYI I am NOT @admin-elvistrujanovic. What he did to fix it was using kernel 5.10 on his system, but I want more info. What is your brunch version, chrome OS version, and recovery image? |
|
@tejasraman brunch version r100 chromeos 100 rammus ,ddr3 4gb ram |
|
Warning: Don't update to r101 on your model |
|
@tejasraman would i be able to update to another version? |
|
Not until @sebanc fixes the Mesa driver issue. |
|
I have this same issue |
|
Hello @soupCodez !
(Ya, that was a bit generic, sorry - but I can't really do much until I know info) |
|
@soupCodez are you still having this issue? |
|
Hello there! I am still having this problem. I am on Brunch r103 with the image for Rammus on ChromeOS v103. My hardware is an HP Probook 67470b that uses a Core i5 3rd gen processor. I am using Kernel 5.10, but I had the same behaviour with kernel 5.4 and 5.15. I have Brunch installed on my USB key using the instructions from Github (not any other video instructions). When I get to the part where I want to install it to the HDD, I cannot open crosh. Troubleshooting steps I've tried:
Any help would be welcome. Thank you! |
|
Hi @dhomas1 ! I can provide you with an (up to date) video tutorial if you want. Tejas |
|
@dhomas1 have you managed to get it working? |
|
hey there @tejasraman . Can you suggest brunch type for Intel(R) Celeron(R) CPU B830 ? |
|
@Not-Dhanraj The best image I can give you is Caroline. I'll give you a tutorial but I need to know if you're using windows or Linux. (Edit: read your GH page. Arch? Don't use the btw line on me 🤣) Currently using fedora KDE but I have a partition with endeavorOS (Sway) and I can tell you what to do from there. Tejas |
|
If you see #1677 I'm not sure if your celeron will work however it might. If you could try Caroline + brunch 107-unstablehttps://github.com/sebanc/brunch-unstable/releases/tag/r107-unstable-20221029) that might work. You can read the official docs. If you want singleboot I can help but dualboot is a mixed bag (especially when it comes to fedora) |
|
I don't intend to use btw line anyways lamo😂 |
Yeah, i want singleboot. If it'll work i'll upgrade to a 150 gig ssd. |
|
I mean it will but unstable is never unstable. I wanted to replicate my Sandy bridge setup but stable should work. Single boot :) I can help (BTW I don't use Arch) |
|
I'll give you a tutorial in any form you want. |
Video tutorial would be amazing 😅 |
|
Will do! Want me to do it on arch? |
Do it with whatever you have right now, or whatever you are comfortable with😁 |
|
I have an arch partition on my main PC. I'll film it today or tomorrow and send it in to you. |
|
Thanks! |
|
I'm still trying to make this into a video tutorial but here is a text tutorial:
PS the computer needs EFI support for this to work. If you want to try the legacy bios patch download the "mbr_support.tar.gz" from the main brunch repo and extract it into the same folder as the other two right before the last step. |
|
Don't worry abour legacy bios, the laptop in which i am trying to install chrome os supports EFI. |
|
Great... The only Sandy bridge laptop I have is a MacBook with EFI so I never tested the patch. Did the guide work for you? Edit: The reason I mentioned it was that most Windows Sandy Bridge laptops had Windows 7 (no EFI). |
|
Hi, same issue here, I'm running nami r100 over brunch r107 unstable 20221029 on a core i3 3217U processor. Tried different kernels, now on 5.4, tried also ramus r100, crosh keeps on crashing with illegal instruction. Any suggestions welcome! |
|
Could you try Caroline @jmbocn |
|
Hi Tejas, same issue (tried both caroline r100 and r96); plus I cannot login to the system on the graphical GUI. If I switch to terminal mode with CTRL+ALT+F2 I can (1) check that crosh crashes with illegal instruction and (2) on /var/log/messages I see recurrent crashes with lots of ERR from missived calling method .....UploadEncryptedRecord (possibly related to the unability to log in). I reverted to nami r100 which is functional for me -other than crosh-. |
|
Update: I realized I can run crosh, just not interactively. E. g.: |
Yes it did but sadly internet connection wasn't working so installed mint |
|
What's your laptop model? I'll try to help |
|
It is hp notebook 2000. And i cannot tell exact model number right now as i don't have access to that device right now. |
|
When installed chromeos then it connected to wifi just fine and my network was working fine as well but it wasnt opening any website + i was not able to login with my google account. Linux development tools wasn't supported on that device either, so i lost interest as soon as i installed it😂 |
|
You know I hate chromeOS. My school forces a piece of junk Chromebook on me and it's limited (crostini = slow). At the same time brunch is an interesting project (for me) to mess around with. (I even added Linux 6.0 to it recently). I understand what you mean but thanks so much for being so helpful! I think Linux Mint will serve you well - it's served me well 😃. Thanks! |
|
That's weird especially because on an i5-2435M crosh works fine. Your chip has the same/more instruction sets than mine. @admin-elvistrujanovic had this but sadly IvyBridge is not supported (works though). Can you test r107 unstable @jmbocn ? |
|
Hi @tejasraman I'm on brunch r107 unstable, but ChromeOS I cannot update past r100 as I hit a bug that makes the system stall at the login page, see #1546. So I'm quite between a rock and a hard place here :( |
|
Then I'm not sure anymore. |
When I try to open Crosh shell with keyboard, crosh shell constantly close itself. After that when I try run crosh shell from terminal (Ctrl + Alt + F2) I get this error:
illegal instruction (core dumped)
I have latest Brunch and ChromeOS version so - is this bug by Brunch or by Chrome OS. And if this bug by Brunch framework, can this problem be solved. My Chrome OS image is rammus type. I don't have installed anything on my device (Android, Crostini - nothing)
