Subject: git problem

 I seem to be doing something wrong.  I'm trying to bisect to
discover which commit causes my failure to shut down or restart from
gdm on one box (the gdm window disappears, but the background
remains instead of falling back to a console and shutting down).

 So far, I've discovered that the problem is slightly intermittent,
so I'm not labelling a kernel good until it successfully restarts or
shuts down 10 times (indications are that a bad version will fail in
the first 3 attempts).

 Anyway, I've confirmed my supposition that 2.6.24 was good in this
respect, and that 2.6.25-rc1 was bad.  After about a day of
bisection / archive / build /test I went to set an extraversion in
the Makefile (everything had been labelled 2.6.24 because this was
before rc1), and discovered it was already labelled as 2.6.24-rc4,
i.e. far too early.

 Reset, repeated, git came up with the same commits (I wondered if
I'd mispasted at some point).  Looked at the log, this seemed to be
the newest thing available.  Reset, looked at the full log, but I'm
out of my depth trying to understand this.

FWIW, these were the commits it told me to test:

around then.

Confused.  Help ?  Please ?
