Hi all,

By chasing an unresponsive client issue that we observe occasionally, I got my VM to crash with 100% reproducibility.
The error pops up very shortly on the console of the VM before boot (attached).
The test script is quite simple (mount, start processes, kill after 100 micros, umount):

```
while true
do

  echo 3 > /proc/sys/vm/drop_caches 

  mount lab:/ /mnt
  cd /mnt/data/

  for i in *
  do
        sha1sum $i &
        PP=$!
        sleep 1e-04
	kill -TERM $PP
  done
  
  cd /
  umount /mnt

done

```

Best regards,
   Tigran.
