Relevant part of kernel log

When using dual monitors (I'm not sure is correlated but first error shows on
turning second monitor with xrandr) GPU locks up with:

[ 451.840071] radeon 0000:01:00.0: ring 0 stalled for more than 32210msec
[ 451.840077] radeon 0000:01:00.0: ring 3 stalled for more than 32210msec
[ 451.840084] radeon 0000:01:00.0: GPU lockup (current fence id
0x000000000003d501 last fence id 0x000000000003d768 on ring 3)
[ 451.840088] radeon 0000:01:00.0: GPU lockup (current fence id
0x000000000001e67a last fence id 0x000000000001e74a on ring 0)

When turning on second monitor this shows up:
[drm:radeon_cs_parser_relocs [radeon]] *ERROR* gem object lookup failed 0xa
[drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to parse relocation -2!

Old driver 17.2.0-0.20170513 (some git snapshot from 2017-05-13, don't know
exact commit) works fine even when used with Mesa-18.1.6 package (I've reverted
Radeon SI driver only).
