Title:
systemd stuck in
This bug looks similar/related to:
https://github.com/systemd/systemd/issues/10123
https://www.spinics.net/lists/linux-fsdevel/msg132837.html
I've attached my hung tasks (sysrq w).

On 18.04 with kernel 4.15.0-46-generic #49-Ubuntu we hit the hang:
[Apr25 10:10] INFO: task kworker/u256:3:48574 blocked for more than 120 seconds.
[ +0.000106] Not tainted 4.15.0-46-generic #49-Ubuntu
[ +0.17] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this
message.
I think in my case it was this issue that made systemd go into D state:
https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1802021
I was yet to test the fix in that bug but will do it as soon as it's available
on 4.15.+

I have the same problem but the process that gets stuck is dockerd not
systemd.
