Description Oliver Schoett 2004-06-04 11:36:04 UTC 
Loading ati-drivers 3.9.0-r1 fails on my machine with the following messages:

Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected SiS 648 chipset
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: unable to determine aperture size.
agpgart: agp_backend_initialize() failed.
agpgart-sis: probe of 0000:00:00.0 failed with error -22

In contrast, 3.9.0 worked fine.

My hardware is an SiS 648 host bridge and an ATI 9600TX graphics card.  Kernel is 2.6.7_rc2.

Comment 1 Oliver Schoett 2004-06-04 13:37:17 UTC 
This problem was caused by my mistake; sorry. The error occurred,
because I had not patched the kernel for my SiS 648 chipset, as
reported by Oliver Heilmann on the Linux Kernel Mailing list
(Date: Tue, 27 Apr 2004 12:04:13 +0100)

I had wrongly assumed that this was no longer necessary in the
2.6.7_rc kernels.
