I have a very strange phenomenon with my ThinkPad X61, WindowsXPsp3. It
runs normally, but I cannot enter safe mode. Press F8 at boot, select
any one of 3 safe modes, it will end to a blue screen of death showing
something like:
Stop: 0x0000007E (0xC0000005, 0xF76C0211, 0xF78EA700, 0xF78EA3FC)

Before that blue screen, a screen shows a bunch of drivers loading. The
last one is mup.sys. That signed file is fine, however. Something after
that must be wrong.

I used to be able to enter safe mode, but I cannot determine when this
phenomenon begins. Safe mode is used rarely.

Could anybody give some hints?

"0x0000007E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

A system thread generated an exception which the error handler
did not catch. There are numerous individual causes for this
problem, including hardware incompatibility, a faulty device
driver or system service, or some software issues. Check
Event Viewer (EventVwr.msc) for additional information.
"

The suggestion to check Event Viewer, applies to cases where
this happens after the system is running for some time, and then
the error shows up.

The 0xC0000005 is an "Access Violation".

As you rightly assume, it's the "thing *after* mup.sys" causing
a problem. Boot logging is a useless feature. Boot logging shows
what successfully loaded, when the user has no clue as to what
comes next in the failure case.

About all I can suggest, is checking Event Viewer for unrelated
error events, to see if there is a "theme", some sickness in
the system that might be contributing to the problem. As I don't
know of a way to attack the problem head-on.
