The texmf postinstall script can take quite a long time to run, as it
does a lot of font regeneration stuff.  On the other hand I have seen
reports on the list of it hanging.  I don't know squat about TeX but you
can manually run its postinstall script from a regular bash prompt to
find out what the delay/problem is.  It shouldn't have anything to do
with the other problems you have reported.

This means you've got an older and incompatible version of cygwin1.dll
on your system.  Either you didn't reboot when setup.exe said that it
was necessary, or you have some other software installed that includes
its own cygwin1.dll in the PATH, or something else along these lines
occured.

Please read and follow <http://cygwin.com/problems.html> for
instructions on how to report problems -- particularly about attaching
the output of cygcheck.

A BSOD sounds like a hardware or driver problem.

This seems like a symptom of having an ancient cygwin1.dll somewhere in
your PATH.

Not without more information, i.e. cygcheck.
