SubjectIgnorant question: Is via rhine dangerous when on but not networked?
The system that the reports below were from halted again, even after
swapping out the tulip nic for an e1000 (along with the e1000e that's long
been there). In checking through the BIOS settings after the most recent
halt I turned off the via rhine onboard NIC that I stopped using long ago
(wasn't dependable). Then I ran Google's stress test extensively on the
system (http://code.google.com/p/stressapptest/) and Red Hat's
(http://people.redhat.com/dledford/memtest.shtml) plus memtest86, and
everything was happy.

There's been a lot of recent traffic here about workarounds for via rhine
being a crappy NIC, causing system lockups under load. Could merely having
the via rhine NIC enabled in the BIOS (and probably the module loaded for it
on boot) have made the system vulnerable even though the via rhine NIC
wasn't networked?

This is on a Shuttle SK22V10 with an Athlon 2 core CPU, and a 3.2.2 vanilla
kernel.
