Thanks for the link and sorry for the delay.

I actually did find a thread about this problem [1] with the suggested
workaround of restarting all HT CPUs after resume. However for the
workaround to work form me, I had to restart ALL extra CPUs, not only HT
ones (and in fact the problem still occurred after disabling HT in the
BIOS). So restarting CPUs 1 to 3 (I have a dual core with HT enabled)
worked for me, though it's a bit annoying to do -- moreover since I
didn't managed to get this done automatically after resume because it
resulted in a kernel panic on my first and single attempt.

However, the problem disappeared for me in with 270.41.06-1 that was
recently uploaded to unstable, though it doesn't seem to be the case for
everybody [2,3].
I don't close this bug yet because of this, but if you think it's the
think to do, go ahead or tell me.

Thanks again for the help!

Regards,
Colomban
