Hi Olaf,

I don't have access to the machine right now, but I'll send you the output of
lspci later. Is that enough?

I usually use the term "sleep" to mean "suspend to ram" and "hibernate" to
mean "suspend to disk". I don't know if these are the most common terms, but I
do understand the difference between them. I also understand that it is
advisable to have more swap space than RAM (which I do) in order to avoid
problems with hibernation. The thing is that everything was working just fine
until this past weekend, and all of a sudden something broke. The only thing I
can think of is some package upgrade (I run apt-get dist-upgrade almost on a
daily basis), since nothing else has changed. Maybe I should mention that the
only power management package I have installed is pm-utils. I don't have
uswsusp, hibernate or any of the acpi packages installed.

Thank you for your reply,


PS: Is there a way to know which packages migrated from sid to testing on a
given day? If so, and given that some package upgrade was indeed what caused
the problem, that would help me find the culprit.
