Hi, I'm starting this new thread as the old one was getting to off-topic (http://www.phoronix.com/forums/showthread.php?t=6112)
The problem, AGP Cards, with PCI-E chips on them, and thus using the realto bridge chip, aren't getting Interupts assigned resulting in utterly poor performance.
The DMESG snipped from loading/activating the driver:
The relevant part from the Xorg.log:
This has been going on since .. all the 'new' 8.X driver series, the only other driver that was usable before that was 8.34.5.
Since i also have an 9500Pro AGP, i can luckly use that one, which works great. So it's definably driver related. The card also works fine in Windos. (Yes i actually installed ONLY to see if the card would work properly there. I'm that desperate).
So please, Micheal, ATi-devs .. somebody, acknowledge this bug. At least then we don't have to test these drivers constantly, but can simply see in the known bugs section there's still an issue here. Also If none of the beta testers have AGP PCI-e cards, i'm still happy to sign up as an BETA tester.
bug #914 on the bugzilla (http://ati.cchtml.com/show_bug.cgi?id=914) also is about this issue.
