Is it possible that there's no (full?) support for ICH5-R in those kernels? The motherboard is Intel SE7520BD2, exact kernel versions which were tried are: 2.6.9-1.667smp #1 SMP Tue Nov 2 15:09:11 EST 2004 x86_64 x86_64 x86_64 GNU/Linux (FC3 64bit) 2.6.5-1.358smp #1 SMP Sat May 8 09:28:14 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux (FC2 64bit) 2.4.21/22 (RH9) and 2.6.7* (AS3.0) do not show this problem on the board. Does anybody have any idea/patch/hack? Thanks a lot, Edward
