Hi,

thanks for your mail. It seems though that this is independent of the kernel version. I booted into 2.4.22 with LL+preempt and it shows the exact same behaviour as did 2.6.7 vanilla, 2.6.7-bk10-ck5-H3 and 2.6.8-rc1-mm1... I think the card is just not good.. I'm also wondering about the weird lspci -v output which reports no latency for the matrox card [and it's not bus master like all other pci devices i have]..
