[Kernel-packages] [Bug 1991036] Re: ath11k: Freezing kernel when doing s2idle [17cb:1103]
Dear kernel bot, this bug has enough info, and there's a patch upstream that's part of 6.1 that fixes the issue. Though I can say I now hit a failure to restart the device / load firmware after a 2nd resume. This is likely another race; if you just suspend by echo mem > /sys/power/state in a loop, it works multiple times pretty reliable. ** Changed in: linux (Ubuntu) Status: Incomplete => Triaged -- 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/1991036 Title: ath11k: Freezing kernel when doing s2idle [17cb:1103] Status in OEM Priority Project: New Status in linux package in Ubuntu: Triaged Bug description: On ubuntu 22.04, I installed v6.0-rc3 mainline kernel. linux-firmware 20220329.git681281e4-0ubuntu3.4 Sep 01 13:25:13 u-ThinkPad-P16-Gen-1 kernel: PM: suspend entry (s2idle) Sep 01 13:25:13 u-ThinkPad-P16-Gen-1 kernel: Filesystems sync: 0.004 seconds Sep 01 13:25:33 u-ThinkPad-P16-Gen-1 kernel: Freezing user space processes ...
