https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D237271 Bug ID: 237271 Summary: Radeon video card no longer works on 12-STABLE Product: Base System Version: 12.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: sigsys@gmail.com My Radeon RX 560 stopped working after a 12-STABLE update. It coincides wi= th some DRM-related MFCs. I nailed it down to r345932. On r345929 (previous revision affecting 12-STABLE), the card still works. But starting from r345932, loading the amdgpu.ko module prints some DRM console messages and = then the display freezes. The system is still responsive afterward but it somet= imes panics with a page fault not long after. That's with graphics/drm-fbsd12.0-kmod (rebuilt after each update while testing). Here are logs of the kernel messages when the card does not work: kernel: [48] <6>[drm] amdgpu kernel modesetting enabled. kernel: [48] drmn0: <drmn> on vgapci0 kernel: [48] vgapci0: child drmn0 requested pci_enable_io syslogd: last message repeated 1 times kernel: [48] <6>[drm] initializing kernel modesetting (POLARIS11 0x1002:0x67FF 0x1462:0x8A91 0xCF). kernel: [48] <6>[drm] register mmio base: 0xFE900000 kernel: [48] <6>[drm] register mmio size: 262144 kernel: [48] <6>[drm] PCI I/O BAR is not found. kernel: [48] <6>[drm] probing gen 2 caps for device 1022:1453 =3D 737903/e kernel: [48] <6>[drm] probing mlw for device 1002:67ff =3D 400883 kernel: [48] <6>[drm] UVD is enabled in VM mode kernel: [48] <6>[drm] UVD ENC is enabled in VM mode kernel: [48] <6>[drm] VCE enabled in VM mode kernel: [48] ATOM BIOS: 113-C994LP-S01 kernel: [48] <6>[drm] vm size is 64 GB, 2 levels, block size is 10-= bit, fragment size is 9-bit kernel: [49] drmn0: successfully loaded firmware image with name: amdgpu/polaris11_mc.bin kernel: [49] drmn0: VRAM: 4096M 0x000000F400000000 - 0x000000F4FFFF= FFFF (4096M used) kernel: [49] drmn0: GTT: 256M 0x0000000000000000 - 0x000000000FFFFF= FF kernel: [49] Successfully added WC MTRR for [0xe0000000-0xefffffff]= : 0;=20 kernel: [49] <6>[drm] Detected VRAM RAM=3D4096M, BAR=3D256M kernel: [49] <6>[drm] RAM width 128bits GDDR5 kernel: [49] [drm:amdgpu_ttm_global_init] Failed setting up TTM mem= ory accounting subsystem. kernel: [49] [drm:amdgpu_device_ip_init] sw_init of IP block <gmc_v= 8_0> failed -12 kernel: [49] drmn0: amdgpu_device_ip_init failed kernel: [49] drmn0: Fatal error during GPU init kernel: [49] <6>[drm] amdgpu: finishing device. kernel: [49] vgapci0: child drmn0 requested pci_disable_io syslogd: last message repeated 1 times kernel: [49] device_attach: drmn0 attach returned 12 --=20 You are receiving this mail because: You are the assignee for the bug.=
