[Bug 580128] [NEW] Crypt password prompt ignores keypresses for several minutes before responding

Binary package hint: live-initramfs

On a machine running Kubuntu 10.04 with full disk encryption and a
mirror raid setup, the graphical password prompt does not take any
keypresses for several minutes, I would guess it takes about five
minutes before it becomes responsive. During that time, nothing is
echoed no matter what I type, entering the password and pressing enter
does not help, ctrl+alt+del does not work.

I am unsure whether the issue is related to Bug 537793, however on my
machine not a single keystroke is recognized and the problem resolves
itself after some time. From these differences I guess that I am hitting
a different bug, so I am opening an extra ticket.

The issue persists when booting with the nosplash parameter. The
machines boots without a splash screen then, however the password prompt
still is graphical, so there is no difference in the critical part.

Attached are the boot.log and kern.log files. I have found an
interesting line in kern.log, which might be a key here:

May 13 20:05:41 holbach kernel: [    2.702827] device-mapper: ioctl:
device doesn't appear to be in the dev hash table.

On the terminal itself I get another line just below the above one, not
sure in which log file it ends up:

udevd-work[121]: inotify_add_watch(6, /dev/dm-2, 10) failed: No such
file or directory


The problem started occuring all of the sudden one or two days ago, I am not aware of any changes to the system that could be causing the problem. All I have done since then was some debugging for Bug 578732.

Please let me know if you need any additional information. Also, I do
not really have an idea how to debug the issue further, so any hints
would be appreciated.
