[mythtv-users] Kernal messages gone crazy - mythbuntu 10.04

[tortise]

Hi
My box has been crashing recently, ran out of space on my OS drive I 
think, I noted the logs (syslog, kern.log, messages are approaching 5 GB...

messages seem to recycle thru USB ports thus:

Box is running mythbuntu 10.04 and 0.25.
I've made some space on my OS drive, but clearly there is some issue, 
possibly from a routine upgrade?
Can anyone give me a pointer from here please?
