Update: I've updated to linux-generic-hwe-22.04 6.8.0-44 from "proposed" and it has been running fine for about an hour now. I never got this long with the 6.8.0-40 release.
It would always freeze between 5 and 10 minutes after booting, rarely it would last up to 20 minutes. I upgraded only linux-generic-hwe-22.04 (and its dependencies -image -modules -headers -tools) to 6.8.0-44, I didn't update to the new linux- firmware from "proposed". I rebooted to the new kernel and now its been up for an hour. I've stress tested it with opening many python machine learning projects simultaneously, watching many 4k videos with hardware decoding and hardware video rendering simultaneously, and running 3D rendering benchmarks back to back. Its hard to say exactly what fixed it, there are hundreds of backported fixes in 6.8.0-44. Personally I think it was something I/O related. In the 6.8.0-40 kernel I would start seeing incoming and outgoing network packets slowing down to a crawl, and files refusing to open in the seconds just before the freeze. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-6.8 in Ubuntu. https://bugs.launchpad.net/bugs/2077265 Title: Screen freezes with kernel 6.8 (also "i915 driver attached, reenabling gpu turbo"), while kernel 6.5 still works Status in linux-hwe-6.8 package in Ubuntu: Incomplete Bug description: After a kernel update (on 2024-08-14, if I remember correctly), the Gnome desktop freezes, always. This happens sometimes already on the login screen (mouse pointer frozen, no keyboard input accepted). Sometimes it happens a few seconds or a few minutes after login. No further input possible. No change to a text console possible. When I disconnect the USB-mouse and reconnect it, the mouse LED remains dark. Seems that USB is frozen too. This happens with kernel: vmlinuz-6.8.0-40-generic When I boot the previous kernel: vmlinuz-6.5.0-45-generic, no freezes occur and all works well. I managed to switch to a text console before the freeze happened. The attached files were created in a text console as root and then transferred to a different computer in order to report the bug.
