So, I installed the test kernel from bug 1174886 and the freeze happened even with the proposed fix. ----------------------8<---------------------- lpechacek@fmn:~> pgrep -war D 7 kworker/0:1+ipv6_addrconf 1679 /usr/sbin/NetworkManager --no-daemon 1688 /usr/sbin/NetworkManager --no-daemon 1689 /usr/sbin/NetworkManager --no-daemon 1813 /usr/sbin/wpa_supplicant -c /etc/wpa_supplicant/wpa_supplicant.conf -u -t -f /var/log/wpa_supplicant.log 6530 kworker/u16:0+netns 7008 kworker/3:2+events 7010 kworker/3:3+pm 7608 kworker/u17:2+i915_flip 7715 net usershare info 8117 ip --color=auto ne lpechacek@fmn:~> uname -a Linux fmn 5.12.4-1.g92853b5-default #1 SMP Tue May 18 12:02:48 UTC 2021 (92853b5) x86_64 x86_64 x86_64 GNU/Linux ---------------------->8---------------------- The output of SysRq-T is attached. Disabling autosuspend for the network adapter (`echo on > /sys/devices/pci0000\:00/0000\:00\:14.0/usb2/2-4/2-4.3/power/control`) helps to prevent the issue. -- You are receiving this mail because: You are on the CC list for the bug.
