Then I guess my kernel should be unrelated.

So this one changed things a bit!

When it froze, I noticed very high disk I/O, but I didn't have time to SSH
connect to see what it was about before it dropped. Also, I got this in dmesg:

[ 3124.363414] amdgpu 0000:01:00.0: GPU fault detected: 147 0x02e20402
[ 3124.363418] amdgpu 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR  
0x00116A97
[ 3124.363419] amdgpu 0000:01:00.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x02004002
[ 3124.363421] amdgpu 0000:01:00.0: VM fault (0x02, vmid 1) at page 1141399,
read from '' (0x00000000) (4)

It's the first time I got something in dmesg for that madmax freeze!

As Marko asked, should I keep testing with all patches suggested here or using
less?


Finally I've tried with PTS and it froze as well :/ (that was before using the
last patch).
