panic and solid lockup on amd64

[oskar%fessel.org@localhost]

Hej,

i just experienced some problems with a kernel from sources 10 hours old.
transcript from ilo console:

fatal double fault in supervisor mode
trap type 13 code 0 rip 0xffffffff81ebeb39 cs 0x8 rflags 0x10286 cr2 0xffffa8892e56ed88 ilevel 0 rsp 0xffffa8892e56ed90

— trap (number 13) —
Bad frame pointer: 0xffffa8892e56f200

cpu0: End traceback…
dumping to dev 168,1 (offset=8, size=33545543):

and then nothing more.
Any help getting a stable system back would be appreciated…

Cheers
