--7AUc2qLy4jB3hD7Z Content-Type: text/plain; charset=us-ascii Content-Disposition: inline I updated bento last night, and it panicked after a few hours with: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 01 fault virtual address = 0xe5 fault code = supervisor read, page not present instruction pointer = 0x8:0xc052e219 stack pointer = 0x10:0xe00d2c3c frame pointer = 0x10:0xe00d2c64 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 40 (irq29: sym0) spin lock sched lock held by 0xc25a8640 for > 5 seconds panic: spin lock held too long cpuid = 1; Debugger("panic") Unfortunately it hangs there instead of breaking to DDB. The instruction pointer is in: ... c052e000 t propagate_priority c052e360 T init_turnstiles ... I'm currently rebuilding without WITNESS_SKIPSPIN in case this catches it.
