Attempting a dump failed. I'm afraid all for information is the below. The kernel was a non-debug kernel (with debug information). The following is hand typed from a screen shot: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xffffff53f000e2b0 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80f2b11e stack pointer = 0x0:0xfffffe01aeb28970 frame pointer = 0x0:0xfffffe01aeb289f0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 20 (pagedaemon) [ thread pid 20 tid 100089 ] Stopped at pmap_ts_referenced+0x72e: movq (%rcx,rdi,8),%rbx bd > bt Tracing pid 20 tid 100089 td 0xfffff80003eb3560 pmap_ts_referenced() at pmap_ts_referenced_0x72e/frame 0xfffffe01aeb289f0 vm_pageout() at vm_pageout+0xdeb/frame 0xfffffe01aeb28ab0 fork_exit() at fork_exit+0x82/frame 0xfffffe01aeb28ab0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe01aeb28ab0 --- trap 0, rip = 0, rsp = 0, rpb = 0 --- db> The prior (cross) buildworld buildkernel had completed fine. Until yesterday, I'd been running -r325700 or before and had not seen such an issue ever before. I'd been using the virtualbox version for a while before this as well. === Mark Millard markmi at dsl-only.netReceived on Mon Nov 20 2017 - 01:19:21 UTC
