I tried the .26 kernel using the trunk apt shown with no luck.  I still
panics on boot, even with the scanner disconnected.  There appears to
be some difficulty with the interaction of the st tape driver and the
megraid_mbox driver (assuming the problem isn't the st tape driver
period, though I'd expect you'd already have more bug reports if that
was the case, and the panic output on the screen says that the problem
is in the megraid_mbox driver, though I can't see the entire panic
due to it being larger than a single screen).

Regards,

Daniel
