G'day all,
All I have is a digital photo of this oops. (It's 3.5mb). I have serial
console configured, but Murphy is watching me carefully and I just can't
seem to reproduce it while logging the console output.
And as usual, after trying to capture one for 4 days, I get one 10 mins after I've sent the E-mail :)
I think I've just found a way to make this easier to reproduce as /dev/sdd was not even mounted this
time. I just cold booted and started an md5sum -c run on a directory of about 180GB.
