While doing some software builds using poudriere, the system panicked. Unfortunately this system was not configured with swap space, so I cannot do a kernel dump. The system is currently at the ddb prompt. Here is the backtrace: Here is the backtrace from ddb: panic: pmap active 0xfffff8002d2ae9f8 cpuid = 5 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe183958a7d0 kdb_backtrace() at kdb_backtrace+0x39/frame 0xfffffe183958a880 vpanic() at vpanic+0x126/frame 0xfffffe183958a8c0 kassert_panic() at kassert_panic+0x139/frame 0xfffffe183958a930 pmap_remove_pages() at pmap_remove_pages+0x8c/frame 0xfffffe183958aa20 vmspace_exit() at vmspace_exit+0xa1/frame 0xfffffe183958aa60 exit1() at exit1+0x541/frame 0xfffffe183958aad0 sys_sys_exit() at sys_sys_exit+0xe/frame 0xfffffe183958aae0 amd64_syscall() at amd64_syscall+0x25a/frame 0xfffffe183958abf0 Xfast_syscall() at Xfast_syscall+0xfb/frame 0xfffffe183958abf0 --- syscall (1, FreeBSD ELF64, sys_sys_exit), rip - 0x800b195aa, rsp - 0x7ffffffe3e8, rbp = 0x7ffffffffe400 KDB: enter: panic [ thread pid 94762 tid 101570 ] Stopped at kdb_enter+0x3e: movq $0.kdb_why db> Is this a known problem?
