It seems there are a number of separate issues at work here:<BR>
<BR>
First, bug #524871 was originally filed for the "Invalid map handle" message. This message does occur in the case of the freeze when using OpenGL but I don't know if the two problems are related. I find that the "invalid map handle" message is also reported in a different system where the freeze is not happening. Therefore perhaps the freeze issue should be moved to a separate bug report?<BR>
<BR>
If the freezing issue is related to the version of the kernel that would suggest that downgrading the kernel would help resolve the issue. Unfortunately I believe downgrading the kernel makes the fglrx-source unable to compile. Are the kernel and fglrx-source dependencies documented or enforced by the packages?<BR>
<BR>
What would be a path for a work-around to this issue? Does it make sense to downgrade the kernel and try the fglrx drivers from the ATI installer? If so, do they need patches to get going with the version of Xorg in unstable?
