Ref. <http://docs.FreeBSD.org/cgi/mid.cgi?20150415134515.GQ1224> -- similar symptoms. And again, I captured screenshots on a phone, but FreeBSD doesn't seem to recognize the (USB-attached) phone as something that might act like a file system (I guess; I'm a bit new to "smartphones").
In this case, my starting-point was r282623; sources were updated to r282676. I was able to update from: FreeBSD g1-254.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #55 r282623M/282623:1100072: Fri May 8 05:40:49 PDT 2015 r...@g1-254.catwhisker.org:/common/S3/obj/usr/src/sys/CANARY amd64 to FreeBSD g1-254.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #56 r282676M/282676:1100073: Sat May 9 05:50:15 PDT 2015 r...@g1-254.catwhisker.org:/common/S3/obj/usr/src/sys/CANARY amd64 without incident, but the update from: FreeBSD g1-254.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #1590 r282623M/282623:1100072: Fri May 8 06:40:11 PDT 2015 r...@g1-254.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY i386 was only able to build; the panic occurs before we've found any disks, so I can't get a crash dump. I do have a kdb prompt, though, so if someone has a suggestion for something to check, please let me know. (Mind, reading email will be rather awkward while the laptop is exploring the mysteries of a panic, so that might be worth bearing in mind.) Just prior to the bactrace, I see: ... hdaa1: 30 411111f0 15 0 Speaker None 1/8 Rear Kernel page fault with the following non-sleepable locks held: exclusive sleep mutex hdac1 (HDA driver mutex) r = 0 (0xcfef... src/sys/dev/sound/pci/hda/hdaa.c:1571 The most recent relevant entries in the backtrace are: hdaa_configure() hdaa_attach() device_attach() bus_generic_attach() hdacc_attach() device_attach() bus_generic_attach() hdac_attach2() run_interrupt_driven_config_hooks() boot_interrupt_driven_config_hooks() mi_startup() begin() The panic message is "fatal trap 12: page fault while in kernel mode" ... fault code = supervisor read, page not present ... current process = 0 (swapper) ...
