I'll check.  My system only has 80MB RAM, and I run Mozilla, which
pushes a lot of information into the swap space.  When I encounter
this "Host error" problem, tons of messages start spewing into my
logs.  This bogs my entire system down horribly.

<great educational material snipped>

I have reproduced this problem with all the drivers built
into the kernel.

I have also just tried a test pass with 3c59x built in and
USB built as modules.  I booted with only the 3c575 inserted.
I got eth0 running and then loaded usb-ohci (with the enable
bus mastering change added).  This resulted in modprobe hanging
again.

Now I'll try with all modules again and check to see whether eth0
is still usable.

Thanks,

	Miles
