I have a Threadripper 2990WX system that I recently installed an AMD Radeon Pro W5700 into. It runs fine unless I load the amdgpu driver, at which point it panics several seconds after boot: I have enough time to login and run a few commands, but even if I just leave it it'll panic. I'm running: FreeBSD photon.int.bluestop.org 13.0-CURRENT FreeBSD 13.0-CURRENT #0 6db1a3e8098-c273171(master): Thu Nov 26 01:26:17 MST 2020 bcran@photon.int.bluestop.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG amd64 I rebuilt the drm-current-kmod-5.4.62.g20201109_1 port today. The panic is: Fatal trap 9: general protection fault while in kernel mode cpuid = 24; apic id = 18 instruction pointer = 0x20:0xffffffff81002dcf stack pointer = 0x0:0xfffffe016e6ffaa0 frame pointer = 0x0:0xfffffe016e6ffaa0 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 = 4372 (hald) trap number = 9 panic: general protection fault cpuid = 24 time = 1606450595 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe016e6ff7b0 vpanic() at vpanic+0x181/frame 0xfffffe016e6ff800 panic() at panic+0x43/frame 0xfffffe016e6ff860 trap_fatal() at trap_fatal+0x387/frame 0xfffffe016e6ff8c0 trap() at trap+0x8e/frame 0xfffffe016e6ff9d0 calltrap() at calltrap+0x8/frame 0xfffffe016e6ff9d0 --- trap 0x9, rip = 0xffffffff81002dcf, rsp = 0xfffffe016e6ffaa0, rbp = 0xfffffe016e6ffaa0 --- fpurestore_xrstor3264() at fpurestore_xrstor3264+0x2f/frame 0xfffffe016e6ffaa0 restore_fpu_curthread() at restore_fpu_curthread+0x85/frame 0xfffffe016e6ffac0 fpudna() at fpudna+0x3a/frame 0xfffffe016e6ffae0 trap() at trap+0x246/frame 0xfffffe016e6ffbf0 calltrap() at calltrap+0x8/frame 0xfffffe016e6ffbf0 --- trap 0x16, rip = 0x80067137f, rsp = 0x7fffffffd8b0, rbp = 0x7fffffffd8f0 --- Uptime: 1m4s Dumping 4193 out of 130894 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%..91% I've uploaded details (core.txt, dmesg.txt etc.) to https://bsdio.com/freebsd/crashes/2020-11-26-amdgpu/ and the vmcore file is available on request. -- Rebecca Cran
