  Laptop hangs on suspend

Status in linux package in Ubuntu:

Bug description:
  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.
