SNA causes problems with DRI_PRIME

When I run Xonotic on discrete gpu (DRI_PRIME=1), sometimes I see only black
screen, and dmesg is full of these messages:
[ 5172.729073] [drm:radeon_cs_parser_relocs] ERROR gem object lookup failed
[ 5172.729078] [drm:radeon_cs_ioctl] ERROR Failed to parse relocation -2!
Radeon starts working again only after reboot.
This doesn't happen with UXA, so I think the problem is related to SNA.
Tested on versions 2.20.13 and 2.21.3 - no difference.
