I recently diagnosed a interesting bug:

With a fresh booted box I can watch any Video with
mplay -vo=xv

No problem.
As soon as I do a suspend/resume cycle and try the same fglrx will produce a nice (well not so nice ASIC hang and I need to login remotely to reboot my box.

If I use -vo=gl2 mplayer plays the same video without any problem!?

Some other intresting thing is: The Bug trace from asic hang mentions something like "reiserfs_rename"

But I dont use reiserfs! All my partions are ext4..

This is not realy critical as I know the work-around.. but perhaps interesting for some dev
