problem booting 2.1.12[45]

In this hectic time before a 2.2 release, I hope you will forgive a
short interruption for a what is undoubtedly a naive question from
someone who still has a very long way to go before qualifying as a
kernel hacker.

I run a modular, all scsi SMP personal rh-linux machine, with one
BusLogic BT-958 and one 2940, and started experimenting with dev
kernels at about 2.1.108, to try to get a jump on what I would need
to do for 2.2. I thought I had managed to do that, mostly digging
out what needed to go into conf.modules, but I've run into a module
problem in 2.1.24 and 25. I compiled these kernels and their modules
with the same configuration that I used for 2.1.122, which is
currently running quite nicely. There were no errors in make's
output, but I am greeted with this familiar litany on boot:

kmod: failed to exec /sbin/modprobe -s -k block-major-8 errno = 2
VFS: cannot open root device 08:03
kernel panic: VFS unable to mount root fs on 08:03

It appears that depmod is not being successfully run for the 2.1.125
modules since no modules.dep file appears in the modules directory.
Running "depmod -a 2.1.125" with 2.1.122 generates a lot of unresolved
complaints but it also generates what appears to be a legitimate
modules.dep, however the same boot problem persists. I also added
"alias block-major-8 sd_mod" in conf.modules, but still no joy.

I am not sure what other information might be relevant, but, of
course, I would be happy to provide anything that might be helpful.
I have prepared myself to be embarassed by having some obvious
oversight pointed out to me, but it is certainly not obvious to me
right now.

Thanks,

Mike McKernan
