Hardware was my initial thought, perhaps something related to USB and
switching the KVM. Of course, operator error and/or software are usually the
culprit, so I spent a good bit of time last night rerunning that mongo
config under a number of scenarios, none of which reproduced the errors. 

I'm not a hardware guy, so here's a sample of the messages when switching
the kvm between linux and the other machine.

In addition, here is a sample of /var/log/messages from a start-up. If vs
suspects hardware, perhaps something will stick out in here:

syslogd 1.4.1: restart.
 kernel: klogd 1.4.1, log source = /proc/kmsg started.

 kernel: Symbols match kernel version 2.6.8.
 kernel: No module symbols loaded - kernel modules not enabled.

...
This seems strange. I definitely have kernel modules configured in:

# Loadable module support
#
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
CONFIG_MODULE_FORCE_UNLOAD=y
CONFIG_OBSOLETE_MODPARM=y
