Please attach the full output of dmesg, or at least more drm/radeon messages
before these.

Did this work before, e.g. with an older kernel?

Sounds like it might be a different / additional problem, which would need to
be tracked separately.

That's most definitely a separate issue, which would need to be tracked in an
fglrx bug tracker.
