System video freezes randomly during the day while working on the system normally (no 3D). Logfile shows only: May 17 11:18:00 ws01 kernel: [11831.268044] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, last signaled seq=2081253, last emitted seq=2081256 May 17 11:18:00 ws01 kernel: [11831.268051] [drm] No hardware hang detected. Did some blocks stall? If I can assist any further, please tell.
Can you load kernel with grub command line amdgpu.vm_update_mode=3 to force CPU VM update mode and see if this makes the issue go away ? Andrey
Added the grub cmdline and will investigate
Hello, I think I'm experiencing the same problem here. My Ryzen 5 2400G system freezes often, especially under some high cpu and disk activity, even after the "Typical Current Idle" UEFI workaround. Sometimes I could reboot with sysrq, most of the times I need a hard reset. The freezes never leave a message in kernel log until today, after 2 months I built my machine. 6月 16 23:29:00 sfc-DESKTOP kernel: [drm] No hardware hang detected.

CPU runs at stock 3.6GHz, memory 16G DDR4, running at 2133MHz, no overclocking.
Not sure if this is related to bug #199653, which concerns freezing on the 2500U and 2700U. It hasn't received any attention from AMD or other kernels devs but there is more information that could potentially be useful. I tried amdgpu.vm_update_mode=3 but that didn't help.
Those two bugs are unrelated.

Are you seeing sdma0 timeout message when the system freezes like muelladi above ? I expect amdgpu.vm_update_mode=3 to help only in that case.
(In reply to Andrey Grodzovsky from comment #6) > Are you seeing sdma0 timeout message when the system freezes like muelladi > above ? I expect > amdgpu.vm_update_mode=3 to help only in that case. I haven't been able to get any information as I have been unable to access the system following these freezes. Judging by the output from the other reporter, they do indeed seem unrelated. Sorry for the noise but some attention on that issue would be hugely appreciated. It's so bad, I've considered selling the laptop.
Today I tried the amdgpu.vm_update_mode=3 option, and my computer still freezed. This time no log was recorded.
I found I'm able to reproduce the freeze when I'm compiling two Android ROMs at the same time while browsing or something else. It will freeze in at most 3 hours. I have a 300W PSU, and 2 SSD + 1 HDD storages. Android sources are stored in the HDD. This time I can reboot with sysrq, seems not a PSU fault.
So far I have not had any more freezes during normal, non-3D work.
Other Raven Ridge users have reported that updating to the current microcode files from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu has fixed stability issues. Make sure your system BIOS and CPU microcode are up to date as well.
I updated to the current microcode files at linux-firmware.git. Today I replicated the same workload, and my computer freezed in just 5 minutes! Even sysrq does not work. I have to do a hard reset. Still, no log was recorded. I have an Asrock AB350M-Pro4 motherboard, with latest UEFI version L4.82.
(In reply to notsyncing from comment #12) > I updated to the current microcode files at linux-firmware.git. Did you update the microcode files in the initrd as well?
(In reply to Michel Dänzer from comment #13) > Did you update the microcode files in the initrd as well? I just copied the files to /lib/firmware. I'll try with update-initramfs.
Still freezed under two Android source compilation + 2 intellij idea + 10 firefox tabs + EVE online playing after 3 hours. Sysrq does not work, need hard reset. No log was recorded.
What kernel version are you using ? We can try and figure out what was the last commands in HW before you experienced the page fault. You can clone and install our register analyzer from here - https://cgit.freedesktop.org/amd/umr/ Then launch your X with ENV variable GALLIUM_DDEBUG=always to dump all the 3D commands into files in ~/ddebug_dumps/ Run your workload. After you again experience the GPU page fault please provide the following outputs sudo umr -lb sudo umr -O verbose,follow_ib -R gfx[.] sudo umr -O bits -wa sudo umr -O many,bits -r*.*.mmGRBM_STATUS sudo umr -O many,bits -r *.*.HEADER_DUMP sudo umr -O many,bits -r *.*.CP_EOP
(In reply to Andrey Grodzovsky from comment #16) > Then launch your X with ENV variable GALLIUM_DDEBUG=always to dump all the > 3D commands into files in ~/ddebug_dumps/ Would you mind telling me how to add this variable? I googled and cannot find any information. Should I add it to /etc/X11/Xsession or something else? Thanks very much! I'm on kernel 4.17.2-041702-generic, Ubuntu 18.04, mesa 18.1.1-1ubuntu1~18.04.0~ppa1
BTW, I'm using KDE plasma 5.13 with sddm.
(In reply to notsyncing from comment #18) > BTW, I'm using KDE plasma 5.13 with sddm. You just prepend this before command to start your graphic stack. You need to manually run your graphic stack from command line and add this before. E.G. for me on Ubuntu I will disable graphics launch on boot from GRUB. Then from terminal I will run GALLIUM_DDEBUG=always service lightdm start

Is that normal? I checked myself, you need to use this variable with specific graphic application you are running, can you pinpoint what graphic work is going on while you have this faults ?
In fact there is no specified graphic work. I just put an Android source compilation running and go to bed, besides only firefox and dolphin running. The next morning, I found the machine has already freezed. Still no log. The log I posted is just a lucky one. Would you mind telling me if the umr had some system-wide debugging methods? Or should I make a netconsole to see if there was anything?

UMR is system wide any way, it's memory/registers/HW debugging tool. you can provide the UMR outputs I asked before once the freeze happened assuming you still have SSH access (which seems like you don't). Since the memory faults you experience are clearly due to some graphic rendering activity maybe you could try to isolate the app which triggers it, repeat what you do but close both firefox and dolphin and check if this still happens. If not try to find which of them was causing this and then we can run it with MESA debug flags.

Created attachment 277101 [details] Kernel log from serial port when it freezes Finally got logs from serial port when freezed. Seems my problem has nothing to do with amdgpu. Maybe I should file a new bug.

I may be off the mark but that looks more like bug #196683. Have you tried adjusting "Power Supply Idle Control" in the BIOS (if you have it) or using zenstates.py to disable the C6 package state?
I've set that option to "Typical Current Idle" and still freezes. The logs in 196683 points to RCU, which seems not my case. I suspect it's due to the zram. Now I'm trying to reproduce it with zram disabled.
Now about half a month passed, and my machine is running fine with zram disabled. No more freezes. Seems my problem is related to zram, not this bug, while the "ring gfx timeout" error never happened again. Thanks for everyone who gave me advice.
notsyncing, can you close this ticket then ?
