Thanks Michel. I tried replacing my radeonsi_dri.so (only) with one built from
the 10.3 branch at 5878e18, which includes the fix for <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [radeonsi] X11 can't start with acceleration enabled"
href="show_bug.cgi?id=60879">bug 60879</a>. The display
is still grey static, but now there is no "mouse cursor" kind of thing.
Periodically it cycles between static and blank screen. After a couple of
minutes of this, the box locks up hard.
The syslog output is a little different as well. Now I see some lines like:
Dec 28 10:57:00 kano kernel: [drm:atom_op_jump [radeon]] *ERROR* atombios stuck
in loop for more than 5secs aborting
Dec 28 10:57:00 kano kernel: [drm:atom_execute_table_locked [radeon]] *ERROR*
atombios stuck executing C238 (len 254, WS 0, PS 4) @ 0xC262
Dec 28 10:57:00 kano kernel: [drm:atom_execute_table_locked [radeon]] *ERROR*
atombios stuck executing B798 (len 106, WS 0, PS 8) @ 0xB7ED
which were not there before. I'll attach the full syslog shortly.</pre>
