46 Stating the obvious, it seems that the kernel is struggling and indeed you may
47 have come across some nasty kernel bug. However, it could well be that it is
48 not related to the kernel you're running, or your kernel config. It could be
49 a problem with the power supply being faulty and causing these lock ups.
50
51 Unless someone else comes up with a better idea to troubleshoot it further, I
52 would consider replacing the power supply with another of a known good
53 condition.
