Added by Gordon, Jun 26:
/var/log/isfs/kernel has those dmesg messages, with timetags
Jun 23 16:49:50 low kernel: i2c i2c-0: i2c_pxa: timeout waiting for bus free Jun 23 16:49:53 low last message repeated 5 times Jun 25 09:27:58 low kernel: handle_IRQ_event called 4 times for IRQ 3 Jun 25 17:46:14 low kernel: handle_IRQ_event called 4 times for IRQ 3
So it turns out those messages are old and aren't much help.
I believe a adn/aup will bring it back too.
I just updated the xml on low so that every sensor has a timeout. That should help to recover from this situation more quickly.
