Summary: DRM git broken for VT8623 rev. 3 (CLE266)
Product: DRI
Version: DRI CVS
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM modules
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
Kernel version where bug don't exists: 2.6.21-rc4-git5
Distribution: Gentoo
Hardware: VIA EPIA M10000, CLE266 chipset with integrated CastleRock graphics
Good "via" module version seems to be: 2.11.0 20061227
Bad "via" module version seems to be: 2.11.1 20070202
Gentoo's x11-drm package replaced kernel "drm" and "via" modules with version
from git. After reboot X screen was trashed. No window background, no window
frames. Only text visible, but printed on previous lines. Problem dependents on
"EnableAGPDMA" option set in xorg.conf and I can't reproduce it in my current
kernel. I can't reach broken commit with git-bisect nor git-reset because I'm
using Linux 2.6.21-rc4 and I need "fix build for 2.6.21-rc1" patch to compile
drm modules. For older commits bug seems to occur only if OpenGL is used (about
10s). Gears from glxgears command aren't visible after it hit. Switching to
text console and backward is causing lockup.
Output of "lscpi -v" command:

After trying today's git I found these errors in log (this is first time, no
errors earlier):
