[Openchrome-users] Segfault with latest git master on cle266

[matt Jarvis]

Hi James

I've applied those patches ( and also tested with latest git master as I
noticed they'd been committed now ). The mode detection looks like it's
working correctly, but now X appears to start and immediately cleanly shuts
itself down, which looks like it's connected with this kernel message which
I get at that point :

[drm:via_build_sg_info] *ERROR* Invalid DRM bitblt alignment.

I'm testing this remotely so can't see what screen output I'm getting, but
it looks like mythwelcome ( the first X program to start up ) starts and
then the DRM error above happens, then X shuts down :

Last two entries in /var/log/messages are

Jan  3 11:25:51 (none) local0.info mythwelcome: Unknown log level: warn
Jan  3 11:25:52 (none) user.err kernel: [drm:via_build_sg_info] *ERROR*
Invalid DRM bitblt alignment.

I get the same behaviour on both my cle266 and cx700 based boards.

I'm testing this with minimyth, and in their dev tree the kernel has
recently been updated to 3.6.11 from 3.6.10 so it's entirely possible this
has been introduced by that change. My cx700 board works fine with
openchrome git 0db1c3c and the 3.6.10 kernel.

I've attached my Xorg log from the cle266 - the log output on the cx700 is
pretty much identical.
