[Kernel-packages] [Bug 2057484] Re: kernel worker event freezes during traffic on iwlwifi
I'm not sure the problem I'm having is exactly the same, but I also can't get any kernel after 6.5.0-21 to properly boot up on my laptop with an Intel wifi card. I'm attaching the portion of kern.log where a bunch of kernel worker tasks are reported as timed out; that happened, IIRC, after I tried to shut down the system by hitting the power button. The system wasn't really usable since most processes weren't able to start, so I couldn't really do a lot of investigation. Even trying to do "sudo blah" or just "ifconfig" would hang indefinitely. If it's any help, I have a bunch of options set for the Intel wifi driver: options iwlwifi power_save=0 options iwlmvm power_scheme=1 options iwldvm power_scheme=1 options lwlwifi bt_coex_active=enable ** Attachment added: "Kernel worker timeout reports from kern.log" https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-6.5/+bug/2057484/+attachment/5756935/+files/kern.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2057484 Title: kernel worker event freezes during traffic on iwlwifi Status in linux-signed-hwe-6.5 package in Ubuntu: Confirmed Bug description: With traffic on Intel Wifi 7 BE200 card, For a while kernel enter 100% cpu usage on a worker event thread and kworker/0:0-events_freezable is in D state.

[Kernel-packages] [Bug 1872001] Re: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0
I was also running into pretty horrendous graphics perf (with bionic), and fixed it after I did the following (did all at once so not sure which one did it): - updated to the 5.3.0-51 kernel - set the java2d option to opengl (from #82) - although I had issues in other apps too - updated the Xorg server to xserver-xorg-hwe-18.04 (+ other hwe drivers) My guess is that the last one is what did the trick. Much better for the last couple of days. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1872001 Title: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0 Status in linux package in Ubuntu: Confirmed Status in linux source package in Eoan: Confirmed Bug description: Hi, Since update to HWE kernel 5.3.0-46-generic I am experiencing frequent (every couple of minutes) GPU hangs and reset manifesting as 2-3 seconds freezes of the GUI (other than the mouse pointer).
