re all,

i report this bug after extensive testing and having carefully checked
the udev rules i'm using in making my distribution.

i am running linux-2.4.15, testing it on a VGA Intel Corporation 82830
CGC [Chipset Graphics Controller] which has DRI regularly supported in
XFree86 and Xorg with the auxiliary kernel drivers i810 and i915 and the
X driver i810.

i report DRI is perfectly working on X.org 7.0 with udev-075 and 2.4.15

but, keeping exactly the same setup, all subsequent versions of udev
fail in creating /dev/dri/* and /dev/agpgart devices.

any clues about the cause?
thanks in advance for any help in sorting this out,

ciao

What distro are you using?

What are the errors you see?

Have you run udevtest on these devices?

thanks,

Another of these buggers that bypasses the class core:

drivers/char/drm/drm_sysfs.c:
  static ssize_t show_dev(struct class_device *class_dev, char *buf)

That needs to be fixed in the kernel.
