    SubjectRe: 2.5.66: slow to friggin slow journal recover

    It finally didn't kill it. This is what it's like when it's not doing
    anything (ie no disk access). Once Again, after this I had to ^c it to
    get some progress on the booting (ie let mount handle journal recovery).

    Something I realised last night though is that this happens when I get
    sudden power off. Not everytime but most of the time and as such reboot
    -f wont help as I think that lets everything finish nicely.

    Martin's distress was in contrast to the bitter satisfaction of some
    of his fellow marines as they surveyed the scene. "The Iraqis are sick
    people and we are the chemotherapy," said Corporal Ryan Dupre. "I am
    starting to hate this country. Wait till I get hold of a friggin' Iraqi.
    No, I won't get hold of one. I'll just kill him."
