Entire core dump
Hi!
I just upgraded our firewall from 11.0 to 11.1-p4, however after about ~35-45
minutes it panics. After some poking around i saw there were quite a bit of
changes in the mps driver so I'm guessing a bug snuck in there somewhere.
I'm happy to apply a debug patch to get you more information to sort this out
if you need to.
It panics with this stracktrace:
Unread portion of the kernel message buffer:
panic: vm_fault: fault on nofault entry, addr: fffffe00003eb000
