Created attachment 299587 [details] git bisect log for the issue Shutdown / reboot takes appropriately half a minute extra to complete with 5.16-rc1 Bisected to b637108a4022951dcc71b672bd101ebe24ad26d5 blk-mq: fix filesystem I/O request allocation 5.16-rc1 with just that commit reverted does not have the issue. I tried applying https://lore.kernel.org/linux-block/20211115075650.578051-1-ming.lei@redhat.com/ and the issue was still present
What storage devices are you using? A dmesg from a fresh boot would be interesting to see, including a mount output.
