Re: Upgrade to 2.6.32-5-amd64 failing miserably

        There's another, possibly very significant oddity.  Right now, when the
old kernel boots, it exhibits exactly the same symptoms for /dev/md0,
but not for the other arrays, the only obvious difference
being /dev/md0 is comprised entirely of disks whose udev names
are /dev/sdX, while the other arrays are built entirely from members
whose names are /dev/hdXY.  In the new kernel, all the drive names
are /dev/sdX.  For some reason, it is trying to assemble all the
members twice, the difference being the arrays assembled from PATA
targets are being stopped in the old kernel before the second attempt
to assemble the array, but not the new:

        Dmesg | grep md from the old kernel:

        Compare that with the new kernel:
