I've recently encountered an upgrade problem that I didn't report.

I've upgraded an Asus EeePC 900 from 10.10 to 11.04 using the GUI
(update-manager).  Due to the extremely slow SSD on the Asus the upgrade
took about 10 hours, so I left it unattended.  The next morning I found
that X had either crashed or restarted, leaving 'dpkg' and 'natty'
processes stuck in the background without a tty (strace on the dpkg
showed it was blocked trying to write to fd 1).  I managed to recover by
killall'ing dpkg and natty and doing a dpkg --configure -a over ssh
(the gdm login screen was completely nonresponsive to keyboard and mouse
input).

I haven't filed a bug because I've no idea what happened (neither
/var/log/Xorg.0.log nor /var/log/Xorg.0.log.old didn't have anything
suspicious like a stack trace; there were no segfault notices in dmesg).
Should I have?
