Hello,

installing NetBSD-1.5.1 on a Compaq Armada 1750 using boot
floppies bootlap[1,2].fs and CD iso image only works with
my 3Com 3c575CT cardbus ethernet adapter detached (otherwise
it will not be found both in the installation process and
at later boots). After installation of NetBSD and reinsertion
of the network adapter it was detected at boot time.
But at the end of the boot process it finishes with 
"ex0: device timeout". It seems to be an interrupt conflict.
Please, let me know how to solve this problem. Thanks!

Here is the corresponding dmesg log:
