https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276985 --- Comment #7 from feh@fehcom.de --- Hi Vlad, thanks for your comment. On my side, there is a bit more history: a) Before I used the current MiniPC with AMD Ryzen 5, I had a similar device with Ryzen 7, a Gigabyte BRR7-4800. b) Here, I was running Artix Linux in a similar setup. Actually, it is more or less the same KMS-KMOD. One this machine, FreeBSD (14) did not install and crashed immediately. However, under Artix I had the phenomen to get ocassionaly a 'green screen' and the kernel stopped working (similar to my experience with FreeBSD). Thus, at the bottom line: It seems to be problem with the driver making the systerm behave erratic under certain circumstances. Regards. -eh. PS. It is always the same location: kgdb /boot/kernel/kernel -n last vmcore.7 .... #6 0xffffffff8300bc69 at amdgpu_cs_parser_bos+0x639 #7 0xffffffff8300b4ff at amdgpu_cs_ioctl+0xd8f #8 0xffffffff8353cbb6 at drm_ioctl_kernel+0xc6 #9 0xffffffff8353cf65 at drm_ioctl+0x2b5 #10 0xffffffff80da7992 at linux_file_ioctl+0x312 #11 0xffffffff80bb15a5 at kern_ioctl+0x255 #12 0xffffffff80bb12e3 at sys_ioctl+0x123 #13 0xffffffff8100d119 at amd64_syscall+0x109 #14 0xffffffff80fe43db at fast_syscall_common+0xf8 Uptime: 12m50s Dumping 1029 out of 15734 MB:..2%..11%..21%..32%..41%..52%..61%..72%..81%..91% __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:57 57 __asm("movq %%gs:%P1,%0" : "=r" (td) : "n" (offsetof(struct pcpu, Hm => linux_file_ioctl ???
