Description mkkot 2018-06-13 15:46:35 UTC
please help to pin down following problem:

I noticed that there are some glitches in graphics after upgrade: http://img.koci.net.pl/?v=beznazwy.png

It is caused by those packages:
[2018-06-12 20:18] [ALPM] upgraded xf86-video-ati (1:18.0.1-1 -> 1:18.0.1-2)
[2018-06-12 20:18] [ALPM] upgraded xorg-server (1.19.6+13+gd0d1a694f-2 -> 1.20.0-7)
[2018-06-12 20:18] [ALPM] upgraded xorg-server-xvfb (1.19.6+13+gd0d1a694f-2 -> 1.20.0-7)

If you downgrade packages to mentioned versions, problem goes away.

Also my dmesg is full of messages like:

[ 400.831919] VM fault (0x04, vmid 2) at page 1084047, write from 'CB0' (0x43423000) (0)
[ 400.831995] radeon 0000:00:01.0: GPU fault detected: 146 0x0be50014
[ 400.831996] radeon 0000:00:01.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000
[ 400.831997] radeon 0000:00:01.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0400000C

I noticed screen full of those messages while switching screens with alt + ctrl + F1-F7.

I'm running AMD APU on a PC: AMD A8-7600 Radeon R7, 10 Compute Cores 4C+6G.

I don't know if this is enough information, what else I can check?

Please attach your dmesg output and xorg log.
Comment 2 mkkot 2018-06-13 21:29:07 UTC
Dmesg just after logging in: https://pastebin.com/mmnneiGK
Xorg.log (no errors here): https://pastebin.com/356UEFJA

Errors in dmesg are produced all the time and are visible in journalctl with always fresh timestamp.

Comment 4 Michel Dänzer 2018-06-14 08:05:10 UTC
This is probably fundamentally the same as bug 105381.

P.S. In the future please attach files here directly, don't reference external sites (especially not pastebins).
