Last night my iPod finished charging but i left it in the dock (safely disconnected) for some time whilst i continued to use my PB. When done, i decided to listen to some tunes while on my bed and proceed to pluck the iPod from the dock and close my laptop. I plucked the iPod and proceed to close the computer, but as i reach out to close, i see the kernel panic message pop up asking me to restart. I do so and repeat the whole process leading to the panic but didn't get another and haven't had one since. However, i was wondering if i should be worried, i.e are kernel panics ever a one-time/one-off incident or is there something wrong with my machine?. PS i checked the panic log and i think it said something about a USB HCI error thingy......Any thought?
