Subject: Re: Linux 3.2.38

	This is becoming irritating. Clearly bisect isn't capable of
figuring out the bad commit for me, so I'm going to have to walk the commits
myself. *sigh* (The commit it thinks is the one that's causing the problem
for me yet again is very obviously barking up the wrong tree)

git bisect start

	I tested and then retested my rebuild of 3.2.37 and had no problems.
My stock distro kernel of 3.2.29 also has no problems.  As you can see from
this bisect log and the other one I performed previously, a good portion of
the commits in 3.2.38 tend to have no problems, but some of them do for me. 
Irregularly.

	I've noted that the behavior has thankfully been showing up in
console as well as Xorg since before I stopped testing the *last* set of
bisects, so to speed up testing a tad I'm going to stop testing if the cpu
is pegged in Xorg now, and only check console.

Hmm. I suppose on a lark I could try combining the results of the two
bisects for the 'bad' entries and leave out the 'good' ones and see if that
gets me somewhere different. I mean, at this point I know which commits
*don't* work right... The trick is figuring out which ones *do*
