https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D284480 Bug ID: 284480 Summary: graphics/drm-61-kmod: 14.2 amdgpu rx580 stability problem on high zfs load / scrub. Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: x11@FreeBSD.org Reporter: tomek@cedro.info Assignee: x11@FreeBSD.org Flags: maintainer-feedback?(x11@FreeBSD.org) Hello world :-) I noticed stability problem when amdgpu 61 and zpool scrub or high use of raidz2 takes place. I have three ZFS datasets. Two are simple zraid0 third is zraid2. After switching from 13.3 to 14.2 I noticed strange stability problem that makes whole machine unusable and unreliable. It was happening after some hours of= use or daily in the morning (probably some daily tasks triggered problem). Setu= p is 14.2-RELEASE GENERIC AMD64 and drm-61-kmod with RADEON RX580 8GB AMDGPU. Symptoms: * no kernel panic. * long screen freezes. * cannot switch to VT. * keyboard and mouse stops working, keystrokes repeat of skipped, mouse mov= es just a bit. * watchdog is trigerred on on-board realtek ethernet making network interfa= ce go down. * if there are multimedia applications working in the background sound plays with no problem. * machine is unusable. I have recompiled drm-61-kmod, gpu-firmware-amd. Even updated CPU microcode= on boot and late in rc. I have recompiled EFL and Enlightenment, Terminology, = etc. I also changed mobo settings like RAM/CPU/NB/HT clocking. Nothing helped. So I was poking around and found out that triggering `zpool scrub` on datas= ets attached to onboard SATA controller gives the symptoms. Scrubbing zraid0 sl= ows down a bit machine like I noticed every day. Scrubbing zraid2 makes machine unusable. I have replaced RX580 GPU with NVIDIA 1060 installed nvidia-driver and the problem is gone. I am writing this as scrub raidz2 is being done in the background. That would not be possible with RX580 and amdgpu onboard. There may be something in the 61 amdgpu driver that interferes strongly on = the chipset. I think I will switch to nvidia for good. But someone may have similar prob= lem. Thanks :-) Tomek # uname -a FreeBSD octagon 14.2-RELEASE FreeBSD 14.2-RELEASE releng/14.2-n269506-c8918d6c7412 GENERIC amd64 # pkg info drm-61-kmod drm-61-kmod-6.1.92.1402000_3 # pkg info gpu-firmware-kmod gpu-firmware-kmod-20241114,1 --=20 You are receiving this mail because: You are the assignee for the bug.=
