It's possible to have user error with "make oldconfig" on the first try (like getting the
wrong config into it), but if you can reproduce it, it's worth reporting. (And if you can't
reproduce it, you'll have a correct config...)
There was someone recently reporting problems with mounting optical media if he waited more
than 30 seconds after inserting it. It might be related, or it might be a coincidence, but you
might want to look into http://lkml.org/lkml/2008/6/6/170. The thread is kind of inconclusive,
but you might be able to help if you've got a different failure pattern (you need to wait,
while other people need to hurry), but also have a problem with timing and optical media
insertion that came up between 2.6.24 and 2.6.25. It's got things to try, anyway.
Make oldconfig issue has been reported in Bugzilla

I opened a bugzilla bug (#10898) on the make oldconfig issue. Apparently this is a regression reported by Linus himself, and a patch is in the works. Make oldconfig worked fine for 2.6.24.x (as I mentioned in the bugzilla description).
As for the mount(8) CD/DVD issue, well, I'll test that later this afternoon... Time to go to work... I'm still not discounting the possibility that a funky config kernel build combined with my strange mix of hardware (see above--yes, that's all one PC!) might have caused this anomaly.
