I have machine lockups on 2.6.15 with gentoo bits and lastest x11-org

Switching the xorg.conf driver from radeon to vesa works and creates a
reasonable environment. This seems to have manifested itself since
2.6.15-rc1.

The laptop is a Compaq NX9600 with maximum memory and a large disk.

Should anyone care for further data captured from /proc, config, logs
and etc., I'll be glad to forward them along.  I'd also be willing to
debug and/or test whatever suggestions might be made.

Is DRI enabled ? If yes, try disabling it. Recent kernels have the r300
enable DRM, thus X will automatically enable use of CCE acceleration
even for simple 2D, but that isn't very stable on those cards yet.
