    SubjectRe: sata NCQ blacklist entry
    Date
    Hi!

    Just using kernel 2.6.24-rc2 (325d22df7b19e0116aff3391d3a03f73d0634ded).

    When booting the system hangs, using the emergency-sync a couple of times gets
    the system to go on at some point.
    Its always around starting X/Firewall (can't actually say whats done in this
    moment).

    Looking at dmesg i found this (NCQ disabled ...)

    dmesg output
