Bug#656792: linux-image-3.2.0-1-amd64: kernel does not boot since 3.1 under a (strange) Xen anymore
The screenshots don't go back far enough to tell but perhaps the kernel
has detected Xen and has therefore "unplugged" the emulated devices to
allow it to safely use the PV drivers? If this has happened then you
will see messages like:
Xen Platform PCI: I/O protocol version ...
Blkfront and the Xen platform PCI driver have been compiled for this kernel: unplug emulated disks.
very early on.
One way to tell would be to add "xen_emul_unplug=never" to your kernel
command line to prevent this happening and see if it boots with emulated
If this turns out to be the case then I would recommend arranging for
the initramfs to contain the xen blkfront driver and removing that
option again so you end up using the PV drivers (which are much fast
than emulated). This is normally already the case with the default
initramfs tools configuration.
Today is the first day of the rest of your lossage.
