If it has an ati chipset (I suspect it does since I think the nx 6150
does), then try adding this to the kernel command line:

acpi_os_name="Microsoft Windows XP"

According to what I have read the BIOS on almost all ATI based boards
has incomplete ACPI implementation and does a crap job on anything that
isn't claiming to be windows.

If that doesn't do it, then maybe you need to pass an option to set
which timer pin to use and/or ignore, but I don't remember which ones
off hand.
