--- Comment #11 from John F. Carr <j...@mit.edu> --- The stack trace goes through line 759 in trap.c. In my code that is the if statement here: if (td->td_critnest != 0 || WITNESS_CHECK(WARN_SLEEPOK | WARN_GIANTOK, NULL, "Kernel page fault") != 0) { trap_fatal(frame, eva); return (-1); } That prompted me to check td->td_critnest. The WITNESS_CHECK should return 0. I have WITNESS disabled. I have INVARIANTS enabled. Otherwise my kernel is GENERIC. Could we be getting a page fault handling a page fault? I don't know if that can be reconciled with the stack. -- You are receiving this mail because: You are the assignee for the bug.
