Thanks for a clear report.  Basic questions:

 - has this always acted this way since you started using Debian, or
   did the problem begin with an upgrade (i.e., is it a regression)?

 - can you reproduce this with the kernel from sid or experimental?
   (It should be possible to test on a squeeze system by just
   installing recent versions of the linux-image-<foo>, linux-base,
   and initramfs-tools packages.)  If so, we can report this upstream,
   and if not, we can try to find the fix and backport it.

 - please attach output of

	/usr/share/bug/linux-image-$(uname -r)/script 3>&1

   so we can get to know the hardware and drivers involved.

 - any hunches, workarounds, or other weird symptoms?

Sorry for the delay, and hope that helps,
Jonathan
