I've recently begun seeing this, nearly daily, since October 16th.
Beginning October 16, 2009, I've been seeing the same symptoms of (1)
USB connection light on the hub goes out, (2) syslog and dmesg messages
as cited below, (3) some processes hanging on exit, (4) system load
rises, and (5) during system shutdown and reboot, those hung processes
are called out on the console screen.
I've run "testing" for years, updating roughly daily. Currently this is
squeeze, with the last month or so on the 2.6.30-2-486.
I've been running apcupsd since September 6, 2009, well before
experiencing the problem.
I upgraded to 2.6.30-2-486 on October 12, 2009, four days before this
problem, but given the daily problem (at different times of day though),
the kernel upgrade is probably not it.
While I've been composing this message, the problem has recurred!
Stopping and starting apcupsd did NOT resolve things.
Disconnecting and reconnecting the USB-connected UPS didn't help.
System load is soaring now and it looks like I'll have to reboot again. :-(
(I usually go 10-30 days between reboots before this problem, not 20 to
30 hours! Perhaps I should revert to the old kernel, just to see if the
previous kernel is similarly afflicted.)
Here are dmesg excerpts from the instance, yesterday. Today's is
following the pattern, right down to the copy of "screen" I just exited
not cleanly exiting. I'll add an excerpt from today's failure to the
end of things here.
