I use the kernel radeon driver with a Radeon Mobility R300 on a Toshiba laptop. The driver in 2.6.32 works fine and also the non-KMS driver in 2.6.34. However, when I enable the KMS driver (and disable the framebuffer drivers) in the 2.6.34 kernel, my computer freezes after a while of using X. If I don't start X the new KMS driver works fine.
The outputs of dmesg, Xorg.0.log, and glxinfo are attached separately.
In the case when I collected the above output, the bug manifested when I changed back to the virtual desktop of a running audio application (foobar2000 under wine). Access to the USB port with an external hard disk died at that moment. Usually the entire computer freezes (including keyboard, mouse, etc), but sometimes the bug seems to just disable the USB system. It only happens when the KMS driver is active so I file the bug here and not at the USB system or elsewhere.
