Description Ondrej Zary 2008-06-17 01:03:01 UTC

Distribution: Debian unstable

Hardware Environment: x86_64, Radeon X1650Pro PCI-E, Radeon 7000 PCI

Software Environment: Debian unstable

Problem Description:
When I run X on both Radeons (X1650Pro with radeonhd driver, R7000 with radeon driver), the following Oops appears when I issue a reboot command (it reboots successfully after that). When I run X on either of the cards separately, the Oops does not appear.

Marking obsolete, if this is incorrect please try a modern kernel, re-open and update the kernel version
