Subject: 3.0.3 [BUG] unable to handle kernel NULL pointer dereference
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)
