You could experiment with ur BIOS settings and/or ur PCI/ISA slots... if u feel
like it...
I would turn of all power saving features and ACPI and such things - just for
testing dev/cxm of course...

Hmm... U seem to have a much different problem than I had, because: The "dd"
command merely reads from /dev/cxm0 as fast as possible without any delay (e.
g. due to busy network or disc), since /dev/null is quite quick... So I did not
send my "cxm-network-transfer&buffering-tool", because one side of it does
nearly the same as the "dd" command, and because my box was able to do the "dd"
test for many hours...
