2.6.20-rc7 USB issue(?) [disabled by hub(EMI?)]

[Justin Piszcz <jpiszcz@lucidpixels.com>]

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..
