Thanks for reporting it. I think our best hope of solving this would
be to report it upstream.

So:

- can you reproduce this?
- can you reproduce this with a 3.x.y kernel from sid or experimental?
(The only packages needed for such a test from outside squeeze should
be the kernel image itself, linux-base, and initramfs-tools.)
- please attach full "dmesg" output from booting an affected kernel
(and reproducing the problem, if possible).

If the problem is present in 3.x.y kernels, we can check if there are
any relevant fixes upstream newer than the kernel you test (there
probably won't be) and pass this upstream. If it isn't present in
3.x.y, we can try some kernels halfway between to narrow down when the
fix was introduced and try applying the same patch to squeeze.

Hope that helps,
Jonathan

Yep, thanks for the update and sorry it took so long to get to this.
What kernel version are you using these days? (You can retrieve this
information from the parenthesis in /proc/version.) Do you happen to
know if current versions of the squeeze kernel are no longer affected,
too? (The squeeze kernel is supposed to work fine on wheezy/sid, in
case you have time to test.)

Cheers,
Jonathan

I am running Debian's 3.2.0-1-686-pae
$ cat /proc/version
Linux version 3.2.0-1-686-pae (Debian 3.2.1-2) (ben@decadent.org.uk) (gcc version 4.6.2 (Debian 4.6.2-12) ) #1 SMP Tue Jan 24 06:09:30 UTC 2012


I'm running Sid with some Experimental repos enabled.* I've not tried the Squeeze kernel in Sid at all, but how about the other way?* the newer kernel running on the stable 6.0.x ?
