In the dmesg output I found the following:
kern :warn : [ 100.174333] WARNING: CPU: 0 PID: 1055 at block/mq-deadline-main.c:714 dd_insert_requests+0x1b5/0x300 kern :warn : [ 100.521569] WARNING: CPU: 0 PID: 1055 at block/mq-deadline-main.c:474 dd_dispatch_request+0x280/0x380
So these warnings are triggered by:
#if defined(CONFIG_BLK_CGROUP) WARN_ON_ONCE(true); #endif
and in both call stacks I found the following: blkdev_issue_discard(). I will take a closer look.
Bart.
