** Description changed:
On my HP EliteBook 6930p, running Ubuntu 11.10 (Oneiric) suspend and
resume does not work properly.
Sometimes on suspend, and sometimes on resume, the machine completely
freezes. Symptoms are:
- black screen
- cannot switch virtual terminals (aka Ctrl+Alt+F1)
- no response on Caps-Lock (Caps light does not change status)
- cannot reboot using Ctrl+Alt+Del
- kernel hotkeys do not work (e.g., Ctrl+Alt+SysRq+S does not lead to disk
activity)
- sometimes, kernel 'boot' hotkey (Ctrl+Alt+SysRq+B) still works (but
sometimes not)
- no flashing Caps lock (i.e., not a kernel panick)
It doesn't always happen, and it seems like the chances are higher if I
use the machine more intensely. For example, yesterday after a day of
video editing, the first resume already froze. Normally, I can get a
number of suspend/resume cycles before the freeze.
So it was in lucid (10.4) , maverick, natty, and now oneiric (11.10).
+
+ Works in Precise.
