[Bug 598696] [NEW] instantaneous kernel freeze on intel server

[Jean-Marc Le Peuvedic]

Public bug reported:

Binary package hint: linux-image-2.6.32-22-generic-pae

Similar to bug #508699 but occurs on a server system with integrated intel graphics instead of a workstation with VIA chrome.
Similar symptoms of freeze without crash reports nor significant messages in the log files. Mainly detected by loss of ssh session and confirmed by no response to ping. Observed once an interactive graphic session freeze, closely resembling bug #508699.

Freeze happens with gdm stopped and X turned off.

Workaround: run 2.6.31-rt from lucid repos instead of 2.6.32.
