According to Intel's 386 chip documentation, interrupt 14 (="e")
is a page fault exception occurring when paging is enabled and an
error occurs translating a linear address to a physical address.
This error can be caused if the procedure doesn't have privileges
to access the page, or if the page-directory or page-table entry
used for address translation has a zero in its present bit.

A driver going awry can cause this condition. It can be analyzed
by building the kernel debugger into the kernel. When the fault
occurs and the system panics the os should drop into the debugger
which can then be used to display registers and to do a stack dump.
Under ISC Unix, the debugger is documented in section 8 of the
reference manual.
