Sometimes suspend fails on my FS lifebook T5010 tablet laptop with
internal modem for mobile broadband. I am not sure about which package
is the cause. The screen goes blank and the disk access light goes out,
but power is not turned down. (LEDs which normally start blinking stay
steady). The system does not respond and has to be powered off
completely. My impression is that the risk is higher when suspending
after leaving the laptop alone for some time (cron?), and after using
the internal "GSM" (UMTS) modem (sierra). (BTW, the broadband connection
sometimes fails after successful suspend. In that case disabling
network, turning the kill-switch off and on and re-enabling network
helps.)  My impression is also that the problem may sometimes be
triggered by my turning the screen (physical screen only, not the
display mode) to use tablet mode. This morning the last syslog message
prior to the failing suspend was that the anacron main process had
receive the KILL signal. I have had this problem for a long time (I
believe also with 9.04), and recently it's been happening quite
frequently. I haven't reported it before since it's rather vague where
the problem is. It's quite annoying, however.
