https://bugzilla.kernel.org/show_bug.cgi?id=197875 --- Comment #5 from Bart Van Assche (bvanassche@xxxxxxx) --- So command processing got stuck. Since there are two code paths in recent kernels we need to know whether or not scsi-mq was used. Hence please provide the output of the following command: for d in /sys/block/*; do sfx=""; [ -e "$d/mq" ] && sfx=" [mq]"; echo "$d$sfx"; done If the above command reports that scsi-mq is being used for the WDC disk, please check whether the following command resolves the lockup: for d in /sys/kernel/debug/block/*/state; do echo kick >$d; done -- You are receiving this mail because: You are the assignee for the bug.
