Title:
kernel io hangs during mdcheck/resync
Status in linux package in Ubuntu:
Incomplete
Status in linux-signed-hwe-5.11 package in Ubuntu:
Confirmed
Bug description:
It seems to always occur during an mdcheck/resync, if I am logged in
via SSH it is still somewhat responsive and basic utilities like dmesg
will work. But it apppears any write I/O will hang the terminal and
nothing is written to syslog (presumably because it is blocked).
Below is output of dmesg and cat /proc/mdstat, it appears the data
check was interrupted and /proc/mdstat still shows progress, and a
whole slew of hung tasks including md1_resync itself.
