    I can send anything you need. Here it goes some extended log.

    I've noticed that abort are after ACPI debug statements.
    But seems acpi and usb are not sharing irqs.

    abort.log -> 2.6.0test8
    devices -> 2.6.0test8
    kernel.log -> 2.6.0testx where x < 8

    In abort.log, is the paste of the log with kernel 2.6.0test8 in kern.log
    there is a log from 2.6.0test4 or 2.6.0test4-mm

    On previous 2.6.0testx kernels the bug appeared to trigger when ACPI debug
    statements were printed, notice there are aborts after ACPI printks.

    On 2.6.0test8 it seems to be triggered when doing concurrent access to the
    filesystem.

    I would like to help in anyway I can, but ACPI and USB is far beyond my
    kernel knowledge, so I'm not currently able to fix the bugs myself.

    Just ask if you need more information.
    Thanks.

    Regards.
