[kernel-bugs] [Bug 1177009] Leap 15.2 stopped working in KVM with ovmf-ia32 firmware

https://bugzilla.suse.com/show_bug.cgi?id=1177009 https://bugzilla.suse.com/show_bug.cgi?id=1177009#c5 --- Comment #5 from Gary Ching-Pang Lin <glin(a)suse.com> --- The new grub2 package(2.04-lp152.7.15.1) is released at Sept. 22. I compared the difference between 2.04-lp152.7.15.1 and 2.04-lp152.7.12.1, and there is only one patch added: https://build.opensuse.org/package/view_file/openSUSE:Leap:15.2:Update/grub… The patch forced "linux" command to use "linuxefi" first and then the original "linux". "linuxefi" was mostly used in x86_64 for Secure Boot, and maybe it's worth to downgrade grub2 to 2.04-lp152.7.12.1 and see how it works. -- You are receiving this mail because: You are the assignee for the bug.

Maybe you can try those 4 kernels and see which one breaks the system? -- You are receiving this mail because: You are the assignee for the bug.

I should be able to get to it tomorrow, 9/30/20. I'll do my best to get to it ASAP. This laptop has had a RAM upgrade to 32GB, by the way, which you'll probably notice in my next vmstat post. -- You are receiving this mail because: You are the assignee for the bug.

[kernel-bugs] [Bug 1176928] Colour corruption on amdgpu with standard kernel

FWIW, we're going to have the full backport of drm stack for Leap 15.3, so the problem will be fixed there :) -- You are receiving this mail because: You are the assignee for the bug.

[kernel-bugs] [Bug 1177060] drm_calc_timestamping_constants error

https://bugzilla.suse.com/show_bug.cgi?id=1177060 https://bugzilla.suse.com/show_bug.cgi?id=1177060#c3 --- Comment #3 from Takashi Iwai <tiwai(a)suse.com> --- Could you try the older kernel found in OBS history repo and check in which version the problem started? http://download.opensuse.org/history/ If this is a regression during the minor kernel version update, it's easier to spot out. But if it were a major kernel version update (say, 5.7 to 5.8), it's harder... In anyway, it'd be best to report to upstream bug tracker, as the issue is about nouveau. -- You are receiving this mail because: You are the assignee for the bug.

Resumed from sleep, errors began - in the attachment is the journald logfile from wakeup until the stream of dotclock errors began. At times the errors hit the log at the rate of 1000 to 2000 lines per minute. -- You are receiving this mail because: You are the assignee for the bug.
