Bug 1165790

The nouveau kernel driver on Leap 15.1 is rather comparable with 4.19.y kernel, which is a bit old, and likely no chance to get any fix from nouveau upstream, unfortunately.

Still you can try to report to upstream about the issue if it's reproducible reliably, though.

If that is known why doesn't it get an update?

> reproducible reliably

I am not sure how to reproduce it actually. But this is definitely not the first time I experience a system hang due to nouveau. See bug#1139774 (I don't know if it has anything to do with the current one).

You can use the newer kernel version from OBS Kernel:stable or Kernel:HEAD repo, too.  Leap 15.1 kernel version is fixed long long time ago, and won't be newer.

What is the difference between the two please? Also could you provide links to the particular repos (just in case, so I don't make any mistake and use the wrong one).

Why is that? Is it not anti-security not to keep kernel up to date (or at least to back port fixes from newer versions)?

The former is based on the upstream stable branch (currently 5.5.y) while the latter is based on the latest Linus tree (currently 5.6-rc).

You can get the former from
  http://download.opensuse.org/repositories/Kernel:/stable/standard/

Guess for the latter by yourself.

The *VERSION* is fixed.  You're using openSUSE Leap, and that's different from Tumbleweed, which is the rolling release.

Thanks for the link.

Re. Kernel:HEAD I found:

https://doc.opensuse.org/documentation/leap/reference/html/book.opensuse.reference/cha-tuning-multikernel.html#sec-tuning-multikernel-latest

which says:

"Warning: Installing from Kernel:HEAD May Break the System"

Do you actually recommend using this?


As for upstream stable (for which you gave the link): is it safe to stick to it long term?

The stable branch is more stable, obviously.  Kernel:HEAD contains "rc", a release candidate, that is still under development.

Thank you.
So after installing Kernel:stable I am getting new errors:

bug#1166242

Could you please have a look?

Created attachment 832769 [details]
journal

So... today it happened again, with latest stable kernel (journal attached):

5.5.8-3.g1538c30-default #1 SMP Wed Mar 11 09:50:08 UTC 2020 (1538c30) x86_64 x86_64

If the issue still happens with the latest kernel in Kernel:stable (that is 5.7.x), it is time to report it upstream.

No response. Closing.
