I'm running RedHat 7.1 on an HP i2000 ia64 box with a Matrox G400. This has kernel 2.4.3 (with RedHat's patches) and XFree86 4.0.3.

DRI seems to work fine as far as I can tell (glxinfo says "Mesa DRI G400", gears reports ~36 fps with "dri" and "glx" loaded, ~28 fps without).

However, DRI doesn't work with a 2.4.5 kernel. The kernel boots fine, and X starts up fine, and glxinfo again says "Mesa DRI G400", but gears opens a window with nothing in it. After starting gears, I can move the mouse pointer, but X seems dead. The screen looks fine (with the empty gears window), but no mouse events work and I can't kill the server.

I've applied RedHat's agp kernel patches to my 2.4.5 kernel, so drivers/char/agp and drivers/char/drm are identical between the working 2.4.3 and the broken 2.4.5 trees.

Just an additional data point: DRI works fine on 2.4.5 with the 3dfx card. The card doesn't use AGP though.
