I thought i was rid of these, but i had another lockup of the OTG port
on my C3 beagleboard. i am now running an ubuntu lucid image built
today, kernel 2.6.32.11-l12. the board is connected to a USB-ethernet
and hardisk through a USB hub on the OTG port (the other USB port was
even more unreliable).
the lockup seems to only occur when the beagleboard is doing something
intensive. today when a rtorrent was checksumming some large files. in
the past i have triggered it by rsync files around the USB hard disk,
or over the network.

once the lockup has happened i can no longer access the USB disk or
the network.
do you think that my board might be defective?
