Just now I had a boot where it did something different; here's what I
guess is the relevant part of dmesg. This is the same kernel and of
course the same hardware as described in the earlier email. Does the
fact that it's unpredictable mean there's possibly hardware issues?
Still have not seen any sign of trouble on 2.6.30 or earlier.
