[Bug 601666] [NEW] [STAGING] Kernel panic on sleep/resume on Samsung R780 laptop

[theUg]

Public bug reported:

Sometimes (not every time, usually after longer periods of sleep (when I
do not touch computer for several hours at a time)) laptop fails to
resume from sleep resulting in kernel panic (CapsLock indicator is
blinking intermittently, and computer becomes unresponsive, forcing hard
restart). Screen stays black, so I do not see any error messages.

When I was testing this laptop as per Ubuntu Wiki
(https://wiki.ubuntu.com/Testing/Laptop/Lucid/Reports/SamsungR780) it
exhibited similar behaviour: test snr-001 (suspend/resume smoke test)
worked, but extended suspend/resume test (snr-002) resulted with exact
same symptoms (see notes of the test case). That was with fresh install,
now after all updates it still does it.
