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 ?

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.

The HDD led still flashes after this freeze, but in the previous freezes, it
won't flash at all.

using kernel 4.17.0-041700-generic on Ubuntu 18.04, mesa 18.1.1-0~b~padoka0.
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.

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.

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.

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.

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

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

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

I compiled and installed umr and executed "GALLIUM_DDEBUG=always service sddm
start" on a root tty, and no "ddebug_dumps" directory was found in /root or in
my home directory after desktop started. 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 ?

[Bug 199749] amdgpu on Ryzen 2400G freeze randomly

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.

Attached 2 patches if applied to your kernel should tell which process caused
the VM_FAULT please also launch your kernel from GRUB with following parameter
- 
amdgpu.vm_fault_stop=2

After 3 days, I managed to reproduce it again with 2 android compilation and
firefox with kernel parameter mem=4096m (I have 16GB memory). I found that it's
easier to reproduce when the memory is full.

I tried netconsole and could not get it working. I bought a serial converter
and it's on the way. When it delivered, I will try getting the log from serial
port. Then I could try your patches because currently the logs did not get
persisted at all. Thanks for your patches.

I just upgraded to mesa 18.1.3 and kernel 4.17.3. I ran firefox with
GALLIUM_DDEBUG after reboot. It produces these after I opened some tabs and
firefox stopped responsing.

Gallium debugger active. Logging all calls.

[Bug 199749] amdgpu on Ryzen 2400G freeze randomly

Created attachment 277101

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.
