[-- Attachment #1 --] Yesterday's (source-based) update was to main-n280031-11f1dd193af5, and I saw no issues. Today's was to main-n280058-e7a04a110724. My (headless) build machine (which does not attempt to either build or load the module), and uses the GENERIC kernel, had no issues. I note that the machines that load the modules also build them whenever the kernel is built. All machines mentioned here are amd64. The ports tree is at main-n717402-cd0318d52939. (Yesterday, it was at main-n717309-326381de144d.) Installed ports are updated daily. On one of the affected laptops, following the panic, I booted to single-user mode & ran: swapon -a && fsck -p && mount -a That done, I (manually) issued kldload i915kms and (hand-transcribed -- phone is updating): root@:/ # kldload i915kms Fatal tyrap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault bvirtual address = 0x68 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80a92491 stack pointer = 0x28:0xfffffe108ecea5e0 frame pointer = 0x28:0xfffffe108ecea630 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 = 37 (kldload) ...[sorry; I'm getting a bit impatient....] KDB: stack backtrace: db_trace_self_wrapper() at ... vanic() at ... panic() at ... trap_pfault() at ... calltrap() at ... --- trap 0xc, rip = 0xffffffff80a92491, rsp = 0xfffffe108ecea5e0, rpb = 0xfffffe108ecea630 --- pfs_create_dir() at ... debugfs_create_dir() at ... drm_core_init() at ... linker_load_module() at ... linker_load_dependencies() at ... link_elf_laod_file() at ... linker_load_module() at ... kern_kldload() at ... sys_kldload() at ... fast_syscall_common() at ... --- syscall (304, FreeBSD ELF64, kldload), rip = 0x1fbdd4a14e2a, rsp = 0x1fbdd22cde08, rpb = 0x1fbdd22ce380 --- KDB: enter: panic [ thread pid 37 tid 100152 ] Stopped at 0xffffffff80bce523 = kdb_enter+0x33: movq $0,0x1230ee2(%rip) db> I will get a photo up on my Web server once the phone update is done.
