Created attachment 53309 [details] xorg log with the ati driver in fedora16

I have just installed fedora 16 on an "imac11,1", and I still have the same problem. I have attached the xorg log, let me know if there is anything else I could do to help.

I checked that the patch pointed by Comment 55 is include in the linux 3.1 shipping with fedora.

I am going to try the current linus tree and let you know if that helps.

Why are you using UMS? All of the relevant fixes have been in KMS.
