What exactly does 'often' mean? If it's not always, it probably can't (fully)
explain the problem...

Looks like this app ran out of memory. (errno: 1 means EPERM, not sure how that
can happen...)

It's up to the userspace drivers to split it up into smaller chunks that can
fit.


A couple of random things to try would be radeon.agpmode=4 and =-1, disabling
tiling, ... Trying a newer kernel and possibly r300g driver probably wouldn't
hurt either.
