Not sure if this is normal or not, was not doing anything out of the 
ordinary and after secs/3600..  ~ 42hrs this occured?

$ uptime
  19:06:17 up 2 days, 29 min, 10 users,  load average: 0.13, 0.07, 0.06

$ uname -ra
Linux p34 2.6.20-rc7 #2 SMP Wed Jan 31 20:03:09 EST 2007 i686 GNU/Linux

One thing I did recently was upgrade to a newer Intel Motherboard BIOS but 
this is also the first time I have run 2.6.20-rc7 for this long as well.

Any clues?

Mobo: Intel DG965WHMKR
Bios: 1618 (latest)

Could this have been from an apt-get update/upgrade?  Perhaps it upgraded 
something that would probe/look at the USB bus?

It is just the first time I have seen this and was wondering what the 
culprit could be..

It could be.  I just found a bug in the USB core for 2.6.20-rc which might 
be responsible.

On the other hand, maybe it was just some random occurrence.  Noise on the
USB data line or something like that.  Considering your record of
untroubled uptime, this seems likely.  Of course, if it keeps happening
then we should look for a systematic cause.

This happens under heavy I/O + network traffic, it happened again, this 
time under 2.6.20-- is this normal/or would it be considered a bug? 
Because it does retry/re-discover the device.

It would be considered a bug in your device, not a bug in the kernel.
