Crashes for me when the boot scripts start 'xdm'.  Attached tarball has 
'dmesg' output, copy of 'Xorg.0.log', and copy of 'xdm.log' (with same 
backtrace as Xorg.0.log).

Should I put this on Bugzilla, or is evergreen-accel too new?

    Hardware:
Radeon HD 5750

    Software:
linux              2.6.35.2
[merged with drm-radeon-testing merged up to c9f9e91; have also reverted 
5b1714d, and added patch to fix pink vert. line -- not sure if there are 
git commits available yet]
libdrm             2.4.21
mesa               7.9-devel, git be99100
xorg-server        1.9.0
xf86-video-radeon  6.13.99, branch evergreen-accel (bdd41fec)

Note:  libdrm was built against a previous kernel; I can rebuild it 
tomorrow if this is a likely cause of the crash.

Except for this handful of packages I rebuild myself, I am using Debian 
unstable/experimental.  Many of the packages are provided with *-dbg 
versions, but 'xdm' is not one of those.  Possibly I could attempt to 
rebuild an unstripped version of 'xdm' myself; I certainly can install 
debug versions of xorg-server and radeon, but will the backtrace alone 
make use of the debugging symbols?  I'm not quite sure how I can use 
'gdb' in a situation like this to get a better backtrace, but if there's 
a way I'd be glad to try.


Thanks,
Dave W.
