Thank you both for the replies.

I'm beginning to wonder if the two issues I have with 2.6.25[.x] are related in a weird way:

  1. make oldconfig wasn't working right, so I had to make menuconfig and manually select the kernel options. I may have [un]selected a bunch of options I [don'] use for my hardware, thus...
  2. ...the CD/DVD drives may have been acting flaky due to various IDE/SCSI/SATA drivers [not] in the kernel, or functioning differently based on my userspace configuration (I was running Slackware 12.0 when I tried 2.6.25.4 and noted these anomalies) and the odd config used when building the kernel.

Another reason why I was loath to report the CD/DVD not mounting issue was because I have some unusual IDE/SATA hardware in my system (a Promise PDC20271 ATA controller card, a Silicon Image SATA controller card, one of the two DVD burners is IDE whilst the other is SATA), but Linux has ordinarily given me no grief whatsoever for running this odd configuration (I also have a mix of IDE and SATA hard drives and a software RAID-0, but that's another story). Again, I must stress that this could all be a silly case of operator error (I'm good at finding these kinds of bugs ;-) ), or maybe it is a defect that needs the attention of the kernel developers...

I will admit that I'm somewhat of an informal kernel tester; I've compiled and run recent (-stable) kernels for the past 3 1/2 years now (thus explaining why I like Slackware--it works well with vanilla kernels), and I've only had to report one show-stopper (Oops in 2.6.15 due to NULL dereference in usbhid.c).

Thanks again for your replies; I'll look into reporting the make oldconfig issue.

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.
