HI all, I'm getting several BUG: messages in a dmesg of a BL465c 2CPU
/ 8 cores each, all the same of the attached examples along with my
config.gz from /proc/config.gz;
(DMI: HP ProLiant BL465c G7, BIOS A19 09/30/2010)
I've just spotted it and reported here, if more data is needed just
let me know (right now I'm not subcribed to the list, so please keep
me CC'ed, thanks)

Problem is still there in 3.0.4, any hint about what problem it could
be? a NULL pointer dereference seems something we want to avoid :) but
I'm not sure if this could be a "my setup problem" or n ot.
Here latest BUG report in dmesg, same machine, same situation:
