Title:
umount stuck, then kernel panic after hot-plugging drive
Status in linux package in Ubuntu:
Confirmed
Bug description:
I'm trying to unmount a volume, which is:
md raid1 device > dm-crypt > ext4
The machine (and this md device) has had some drive hot-plugged (which
wasn't entirely supported) but seemed to do fine.
I tried unmounting the md/dmcrypt device:
$ umount /this-device
[hangs]
I got this in dmesg, followed by an eventual kernel panic.
