ATI X600 on 2.6.15

ATI X600 on 2.6.15

[Bob Picco]

I have machine lockups on 2.6.15 with gentoo bits and lastest x11-org
bits. A simple startx with three xterms doesn't even render the fonts
correctly.  Eventually the machine wedges and can't be pinged.
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.

thanks,

bob

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.

From xorg.conf:
# This loads the DRI module
#    Load       "dri"

So DRI is disabled.

Not neccessrily. IIRC I disabled explicit loading of dri because it
loaded automagically.

Best is to move the kernel module out of the way

Ben.
