Nonsense! Type E is not a 'catch all', it is a very specific panic, it
is a kernel mode page fault and it isn't ISC specific, the hardware
generates the type of the trap when it occurs and as ANY vendor's kernel
that I am aware of for the i386 are non-pageable this fault should never 
happen when running in kernel mode, and thus you will always panic. The
most common reason that I have seen for this panic to occur is flakey
hardware causing intermittent data corruption.
