Kernel crash during video transcoding
Hi, I installed the port drm-devel-kmod for Plex to be able to transcode videos using the integrated GPU of my Intel Celeron G5900. I'm running r364031 and the kernel is compiled with GENERIC-NODEBUG profile. Transcoding has been working fine for quite a while now but one video transcoding is causing a kernel panic that is reproducible all the time with that particular video. It seems like it's caused by the i915kms module (call of i915_gms_fault() in the stack) : Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xdf fault code = supervisor read data, page not present instruction pointer = 0x20:0x80bdd2b4 stack pointer = 0x0:0xfe00d2be56d0 frame pointer = 0x0:0xfe00d2be56d0 code segment= base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags= interrupt enabled, resume, IOPL = 0 current process = 4611 (Plex Transcoder) trap number = 12 panic: page fault cpuid = 0 time = 1596976796 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfe00d2be5390 vpanic() at vpanic+0x182/frame 0xfe00d2be53e0 panic() at panic+0x43/frame 0xfe00d2be5440 trap_fatal() at trap_fatal+0x387/frame 0xfe00d2be54a0 trap_pfault() at trap_pfault+0x4f/frame 0xfe00d2be54f0 trap() at trap+0x271/frame 0xfe00d2be5600 calltrap() at calltrap+0x8/frame 0xfe00d2be5600 --- trap 0xc, rip = 0x80bdd2b4, rsp = 0xfe00d2be56d0, rbp = 0xfe00d2be56d0 --- _rw_wowned() at _rw_wowned+0x4/frame 0xfe00d2be56d0 vm_page_busy_acquire() at vm_page_busy_acquire+0x141/frame 0xfe00d2be5710 remap_io_mapping() at remap_io_mapping+0x120/frame 0xfe00d2be5760 i915_gem_fault() at i915_gem_fault+0x25f/frame 0xfe00d2be57d0 linux_cdev_pager_populate() at linux_cdev_pager_populate+0x11b/frame 0xfe00d2be5840 vm_fault() at vm_fault+0x3d1/frame 0xfe00d2be5950 vm_fault_trap() at vm_fault_trap+0x60/frame 0xfe00d2be5990 trap_pfault() at trap_pfault+0x19c/frame 0xfe00d2be59e0 trap() at trap+0x3f1/frame 0xfe00d2be5af0 calltrap() at calltrap+0x8/frame 0xfe00d2be5af0 --- trap 0xc, rip = 0x80296659a, rsp = 0x7fffbd38, rbp = 0x80fc0 --- KDB: enter: panic I don't see any crash dump in /var/crash despite having the right configuration and I should have enough space on my swap device (128GB USB drive) : $ cat /etc/rc.conf | grep dump dumpdev="AUTO" $ swapinfo Device 1K-blocks UsedAvail Capacity /dev/gpt/crash0 1213070960 121307096 0% $ cat /etc/fstab /dev/gpt/crash0 noneswapsw 0 0 $ dumpon -l gpt/crash0 Not sure why no dump was generated, is it because the kernel was compiled with the GENERIC-NODEBUG profile ? However I see various KDB options in the GENERIC profile that are inherited by GENERIC-NODEBUG. Happy to recompile the kernel with GENERIC profile if it's required.

cross-build failure on objcopy
When cross-compiling for i386 on amd64 (which has 2 by 4 cores), I get the error below after a previously successful build.
