Hi, I recently switched my port tree from 2021Q2 to 2021Q3, after updating and rebooting my FreeBSD 13.0 system, I started to notice random system freeze, I can ssh to the frozen system, and from dmesg I see:
--- Aug 4 08:58:51 Fryzen495 kernel: drmn0: [gfxhub0] retry page fault (src_id:0 ring:0 vmid:1 pasid:32769, for process pid 100349 thread pid 100349) Aug 4 08:58:51 Fryzen495 kernel: drmn0: in page starting at address 0x000080012c3f0000 from client 27 Aug 4 08:58:51 Fryzen495 kernel: drmn0: VM_L2_PROTECTION_FAULT_STATUS:0x00141051 Aug 4 08:58:51 Fryzen495 kernel: drmn0: MORE_FAULTS: 0x1 Aug 4 08:58:51 Fryzen495 kernel: drmn0: WALKER_ERROR: 0x0 Aug 4 08:58:51 Fryzen495 kernel: drmn0: PERMISSION_FAULTS: 0x5 Aug 4 08:58:51 Fryzen495 kernel: drmn0: MAPPING_ERROR: 0x0 Aug 4 08:58:51 Fryzen495 kernel: drmn0: RW: 0x1 --- The only thing seemed relevent for me between 2021Q2 and 2021Q3 is the newer GPU firmware g20210330 versus g20210224. I downgraged to g20210224, rebooted the system, and it is running stable as before. I found a similar issue here: https://githubmemory.com/repo/freebsd/drm-kmod/issues/78 But didn't try the mentioned work-around. My system is always connected to two external monitors using a USB-C dock, was running for almost 4 months without a reboot with the old firmwares. Shall I open a bug report? I hope this mail helps someone. Regards, Ali.
