--mgiPvHqStUXOBTSF Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Just did a src update from r364296 -> r364341 on amd64 on my bild machine (laptop is still working -- it built firefox earlier, which takes some time). On initial reboot, the build machine panicked: umass0: SCSI over Bulk-Only; quirks =3D 0x4000 umass0:6:0: Attached to scbus6 (probe0:umass-sim0:0:0:0): Down reving Protocol Version from 2 to 0? panic: malloc(M_WAITOK) in non-sleepable context cpuid =3D 1 time =3D 20 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffffff8218d= 440 vpanic() at vpanic+0x182/frame 0xffffffff8218d490 panic() at panic+0x43/frame 0xffffffff8218d4f0 malloc() at malloc+0x20c/frame 0xffffffff8218d540 devfs_alloc() at devfs_alloc+0x28/frame 0xffffffff8218d570 make_dev_sv() at make_dev_sv+0x97/frame 0xffffffff8218d600 make_dev_s() at make_dev_s+0x3b/frame 0xffffffff8218d660 passregister() at passregister+0x3e7/frame 0xffffffff8218d8b0 cam_periph_alloc() at cam_periph_alloc+0x57b/frame 0xffffffff8218d980 passasync() at passasync+0x5c/frame 0xffffffff8218d9c0 xpt_async_process_dev() at xpt_async_process_dev+0x152/frame 0xffffffff8218= da10 xpt_async_process() at xpt_async_process+0x334/frame 0xffffffff8218db20 xpt_done_process() at xpt_done_process+0x3a3/frame 0xffffffff8218db60 xpt_done_td() at xpt_done_td+0xf5/frame 0xffffffff8218dbb0 fork_exit() at fork_exit+0x80/frame 0xffffffff8218dbf0 fork_trampoline() at fork_trampoline+0xe/frame 0xffffffff8218dbf0 --- trap 0, rip =3D 0, rsp =3D 0, rbp =3D 0 --- KDB: enter: panic [ thread pid 16 tid 100068 ] Stopped at kdb_enter+0x37: movq $0,0x10b70f6(%rip) db>=20 So -- it's at the debugger prompt; given sufficient hints, I'm happy to poke at it & report back. Yesterday's (r364296) verbose dmesg.boot is at http://www.catwhisker.org/~david/FreeBSD/history/freebeast.13_dmesg.txt (in case that's useful). Peace, david --=20 David H.
