Unfortunately, the problem has occured during the summer, but at the
time I wasn't particularly interested in solving it until now; it
happened at least 5 kernel updates before, so it would be quite hard to
identify when it happened... I'm currently using the last 2.6.35 offered
for some time (same problem), but I might retry that new 2.6.32 you are
mentioning. I'll upgrade and try, then post back...
