Using the new version of the ati driver (6.6.193) on gutsy the display freezes quickly when using epiphany-browser. The mouse pointer is still moving but nothing else on the display change, switching to a VT doesn't work. Connecting by ssh to the box work, Xorg is using all the CPU and there is no way to stop it. Downgrading to 6.6.3 fixes the bug.
The video card used is an ATI Radeon 9600 pro and the driver is "ati"
Sounds like a GPU lockup. Please attach the config file and log files for both driver versions.

What is the AGP transfer mode set to in the BIOS setup? Which mode does the kernel end up setting with each driver version (dmesg | grep AGP)? Does Option "AGPMode" "4" help?
The bios has "AGP Fast Writing" and "AGP 3.0" in auto $ dmesg | grep AGP [ 33.153134] ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.AGPB._PRT] [ 47.263749] agpgart: Detected AGP bridge 0 [ 47.263767] agpgart: Setting up Nforce3 AGP. [ 47.268145] agpgart: AGP aperture is 128M @ 0xe0000000 [ 75.526133] agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0. [ 75.526331] agpgart: Putting AGP V3 device at 0000:00:00.0 into 4x mode [ 75.526355] agpgart: Putting AGP V3 device at 0000:01:00.0 into 4x mode
the AGPMode option fixes the issue
(In reply to comment #9) > The bios has "AGP Fast Writing" and "AGP 3.0" in auto Does any of the following work as well without Option "AGPMode"? * Option "AGPFastWrite" or disabling Fast Writes in the BIOS * Setting the transfer mode to 4x or 8x explicitly in the BIOS
disabling the fast writing in the bios doesn't make a difference, forcing the agp 3.0 speed to 4x rather than auto seems to work correctly
(In reply to comment #12) > forcing the agp 3.0 speed to 4x rather than auto seems to work correctly What about 8x? I'm afraid this is looking more and more like WONTFIX, as defaulting to 4x caused problems in other setups, so we're currently relying on the BIOS to set up the transfer rate it chooses to be reliable.
the choices are "auto", "4x", "4x8x". What is creating the issue? The video card or the bios? Could the driver default to 4x on boggy cards?
(In reply to comment #14) > the choices are "auto", "4x", "4x8x". So if you choose "4x8x", what transfer rate does it end up using then? Does it work without Option "AGPMode" in that case? > What is creating the issue? The video card or the bios? Could the driver default > to 4x on boggy cards? The issue could be specific to the combination of BIOS, card, AGP bridge and possibly the phase of the moon, so detecting it automatically could be tricky.
If this is still an issue with the ati driver from git, we can add an agp quirk for your card/gpu combo.
