Well, it certainly can fill up (fbcon disabl
The description of the NICs in question as found in
/etc/sysconfig/hwconf
are:
3Com Corporation|3c900B-TPO [Etherlink XL TPO]
3Com Corporation|3c905C-TX [Fast Etherlink]
In one machine it's the first which is getting lots of overruns; in the
other it's the second. Depends on which one is connec

One other thing: if something is diabling interrupts for more than 500
microseconds you can get Rx overruns.
IDE can block interrupts for sev
