Summary: OpenSolaris 64bit panic with kvm-54
Initial Comment:
Wouldn't mark it as a regression per-se as vanilla kvm-53 wouldn't work
(because of the need for IDE patches to get it to run/install), but vanilla
kvm-54 or kvm-54 + the same patches added to kvm-53 and including pre-kvm-55
patches like 71be592a14aa8d127315b2c47bf83cc0d810a341 wouldn't work.
The panic is observed in kvm-54 (--no-kvm runs ok, and --no-kvm-irqchip doesn't
help) while running nexenta OpenSolaris alpha 7 or beta 1 (other OpenSolaris
distributions most likely affected as well) and with the following trace :
panic[cpu0]/thread=fffffffec2de2260: BAD TRAP: type=e (#pf Page fault)
rp=ffffff0001735f30 addr=0 occurred in module "unix" due to a NULL pointer
dereference
