We are chasing a different panic (kern/88725) where dynamic callout are freed but the callout could be still pending. The freed memory can be re-allocated, modified and then cause errors when the timer wheel is checked. After finding this one occurance, I did a complete search of callouts, and I see a potential simular error in the ntoskrnl_libfini() routine in the file /sys/compat/ndis/subr_ntoskrnl.c and a few other places (7 total). I wanted to make verify each of these 7 occurances before issuing a patch. I suspect a simple test loop could verify that this is a simular error as kern/88725. --Mark Tinguely
