Hi alex now the only slot usable is the first one the 16x, before xorg 1.6 the only way for have not apple gpu was the 8x and there there was not issue. Now radeon 4xxx work on 16x with accelerations but freeze, radeon 5xxx and 6xxx work but have (cafedead)only fbdev run. 7xxx run no issue but glamor crash. I open another bug for the glamor. Michel Danze ask a gdb debug of xorg.. but im not able to made it in fedora if i run xorg on gdb i have a black screen with only a cursor on the top of the screen :-/ i will check if on ubuntu mate i will able to make a gdb of xorg. where there i have fence errors on ring 0 and 3 or glitched video. if i delete the glemoregl.so module xorg work i have desktop but no gpu accelerations. i atteached my xorg.log with 7750 The other guys i think have my same issue with radeonsi/amdgpu on ppc hw. why im sure it is an xorg issue or one of xorg component issue (cafedead),because on Lubuntu 14.04.5 i had kernel 4.9 and no issue but xorg was 1.6 -- You are receiving this mail because: You are the assignee for the bug.
