Hmm, it's pretty unfortunate that those buffer checks are inside
PageRepairFragmentation, because that means they are being called when
in a critical section, turning harmless ERRORs into PANICs.  I think
those checks could be copied to another routine to be called outside the
critical sections.

The value 32766 is 0x7ffe, which is a pretty suspicious value.  It'd be
good to see a copy of the problem block (though it'll prove difficult to
determine _which_ is the problem block ...)
