Computer hangs at boot with kernel 4.13.x

Pumpino · 2017-09-24 07:16:22

I tend to run the latest kernel on my machines, even if they're still in staging or testing.

I've run kernels 4.13.1-4.13.3 on my laptop without any issues. However, on my desktop machine, every version of 4.13 hangs at boot.

After selecting Arch in grub, the screen displays a garbled green pattern and that's it. The only solution each time has been to restore a Clonezilla backup, since I'm unable to boot from the failsafe option in grub either.

The desktop machine is an Intel i5 with a Gigabyte GA-Z77x-UD3H (it's 6+ years old).

I figure kernel 4.13 will hit stable soon, so I'd better work out a solution. Any ideas?

What GPU? Also, can you SSH into the machine?

Pumpino · 2017-09-24 07:50:03

Just shared Intel graphics.

I haven't tried SSHing in. In order to test, I'll have to upgrade the kernel again and risk not being able to boot.

Install the lts kernel in addition?

Pumpino · 2017-09-24 07:57:18

So the LTS kernel won't replace the existing kernel like kernels from staging and testing do? I might do that if it'll add it to grub in addition to the existing kernel. It might be good insurance.

EDIT: I installed the LTS kernel, but there's no addition entries in grub.

you'll need to run

#grub-mkconfig -o /boot/grub/grub.cfg

Thanks.

I can confirm that SSH connections fail, so it's not just a display issue. I frequently SSH in from my phone, so it's something that usually works.

Interestingly, kernel 4.13 boots fine in Fedora, so it's Arch specific.

Also try "nomodeset"

If the issue still occurs with nomodeset try intel_iommu=off
Edit
intel_iommu instead of intel_iommo

I tried nomodeset, i915.modeset=0 and intel_iommo=off by hitting "e" to edit when the grub entry was displayed and then adding them one at a time at the end of the "rw quiet" line. Is that the correct way to do it? None of them worked.

"intel_iommu"?
I btw. rather hoped for some useful debug output ;-)

edit: and certainly get rid of the "quiet" - also use the "debug" and other parameters on the formerly linked troubleshooting section.

@seth my mistake I requested intel_iommo=off instead of intel_iommu=off

seth · 2017-09-24 09:31:19

yes, me and pumpipno simply crossposted. post #11 started as answer to you

Pumpino · 2017-09-24 09:49:05

Ahhh, so one of them had a typo. Indeed, we have lift-off with intel_iommu=off. Yay.

So, what exactly does that do and what's the best way to permanently solve the issue? Do I just manually add it to /boot/grub/grub.cfg and check each time there's a kernel update?

seth · 2017-09-24 10:08:32

https://bugs.archlinux.org/task/55629 - likely.

Pumpino · 2017-09-24 12:34:45

Thanks. I guess I can add intel_iommu=off or intel_iommu=igfx_off to /etc/default/grub for a permanent fix.

loqs · 2017-09-24 18:06:42

If intel_iommu=igfx_off cures the issue it is definitely the iGPU otherwise you would need to blacklist modules/module combinations to find out of it is attributable to a particular module.
