--- Comment #2 from D. Moens <[email protected]> --- Ilia, thank you for your instantaneous reply. (In reply to comment #1) > I think you may be the proud owner of multiple issues, as evidenced by the > gpu lockup you get down the line.

In core/engine/disp/dport.c:nouveau_dp_train, prepend a 540000 > value in the first position of the bw_list array. Patched : $ diff nouveau/nvkm/engine/disp/dport.c.orig nouveau/nvkm/engine/disp/dport.c 276c276 < const u32 bw_list[] = { 270000, 162000, 0 }; --- > const u32 bw_list[] = { 540000, 270000, 162000, 0 }; > > Try to get a full debug log (which should include the various DP debug > messages, as well as others), with that change, and the nouveau.debug > settings you were already using (but apparently were either not being picked > up, or something else). Oh joy, I now do get a graphical screen (and high-res VT). Appearantly, I am also bitten by bug #70354 (witness errors.out) ? Please find all logs in attachment (with external monitor detached, for sake of simplicity). Again, thank you for your involvement.
