Hi Kris,
I am a colleague of Jason's, when we were testing this patch the kernel
used had both options set:
option INVARIANTS
option INVARIANT_SUPPORT
Although on several boxes we have failed to cause a kernel panic, only
watchdog timeouts. However the last crash that we reproduced did
trigger several:
bce: need to defrag
Messages on the console before the watchdob timeout occured.
