Network were working and I can log in. Without the keybord - it
generally worked.

In logs:
for example:

^^^^
It's probably the same problem I had.

There is a recent patch enabling the no_overlay=1 parameter and some PCI
quirks to autotune this option. Please try that and, if your board isn't
autodetected, the lspci -vvv output and the exact name of your MB chipset.

I temporarily uploaded the patch to
http://7eggert.dyndns.org/l/scratch/v4l_bttv_no_overlay_linus.patch


I don't know if this is the same problem... Let's hope that it IS the same problem, because the fix that Bodo speaks of has already been included in 2.6.13-rc6:

http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;h=00dd1e433967872f3997a45d5adf35056fdf2f56;f=drivers/media/video/bttv-driver.c

Please test again using Kernel 2.6.13-rc6 and let us know if the problem persists.
