    SubjectRe: [patch] Real-Time Preemption, -RT-2.6.9-mm1-V0.5.2
    Hello all, Ingo,
    Here's a few bugs on boot with V0.5.2, and a question: what's needed to
    get back to the verbose latency messages of previous preempt patches
    (see the terse second log)?
    Thanks.

    ** PCI interrupts are no longer routed automatically. If this
    ** causes a device to stop working, it is probably because the
    ** driver failed to call pci_enable_device(). As a temporary
    ** workaround, the "pci=routeirq" argument restores the old
