Interesting thought - but why does it work OK when piping to /dev/null ? OK,
SCSI driver (or in your case, IDE driver) not then being called. I'm sure
Kenn has another NIC around he can lash in and give it a whirl (and do tell
Kenn - you've got at least me intrigued now). 

BTW you should be aware that there are also issues with the kernel supplied
eepro100 driver - it sometimes hangs up for a period of time. Intel supply
source for a driver loadable module which does not do this.
