Bug Description
A friend of mine has an issue with his fresh Kubuntu 5.04 install. Every 10 to
45 minutes or so, X freezes and he has to CTRL ALT backspace to kill X to be
able to use it again.
Each time X locks up, this message shows up in /var/log/kern.log and
/var/log/messages:
Apr 29 01:32:44 localhost kernel: __iounmap: bad address d4384000
This message shows up in /var/log/
happens:

His video card is an ATI Radeon Rage 6.
X reports it is this in its logs:
