[Bug 1200259] Kernel Panic in bfq_bic_update_cgroup while fstrim after Update to Kernel 5.3.18-150300.59.68.1

http://bugzilla.opensuse.org/show_bug.cgi?id=1200259 http://bugzilla.opensuse.org/show_bug.cgi?id=1200259#c4 --- Comment #4 from Ralf K�lmel <ralf.koelmel@kit.edu> --- regarding the kernel stacktrace it seems related to the bfq IO scheduler. Can you check if you can replicate the problem with another IO scheduler (e.g. none or mq-deadline with the command: echo "none" >> /sys/block/<device>/queue/scheduler) although ? With btrfs and bfq i can't reproduce the problem until now. There seems to be a special runtime condition in your case. -- You are receiving this mail because: You are on the CC list for the bug.
