Actually, I am running slightly modified versions of both
files, although I believe that my modificatiosn are not the cause.
In init/do_mounts.c, I am running the patch that I posted back in ~2.5.48
so that reading /dev under devfs works at all (I think the patch
has fallen through the cracks and I plan to resubmit it, but I want
to get 2.5.51 working first, in case the patch really is the culprit).
The other difference in my system is the removable device
"support" in devfs (having the kernel reread the partition table when
you didn't ask it to, unlike a non-devfs system). I removed it.
Anyhow, I haven't exhausted my debugging efforts, but it has
been a little slow going, so I'm reporting what I know now, in case
anyone recognizes the problem. If nobody beats me to it, I expect to
track down the problem in the next day or so and post a patch then.
