It is and it is not. What I mean is concerning comment 17 "So i did a git log --graph --oneline --all and started to git checkout between those two commits, starting from 2d2f1fd to de92b7a are bad and with commit "ef557ea winsys/radeon: disable virtual memory on Cayman" it started working." If the variable "RADEON_VA" is not set or doesn't exist, from the point commit "ef557ea" kicks in, VM gets disabled. Before that commit, VM is always enabled; from that point, we must be careful. If we want to test after commit "ef557ea" with VM enabled, "RADEON_VA" MUST be set, otherwise it will be disable and will hide the bug. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
