Modified files:
sys/i386/i386 trap.c
Log:
- Don't enable interrupts in trap() if we trapped while holding a spin
lock as this usually makes the problem worse.
- If we get a page fault while holding a spin lock, treat it as a fatal
trap and don't even bother calling into the VM since calling into the
VM will panic when trying to lock Giant before we can get a useful
message anyways.
