insmod crashing on boot

I installed RedHat 4.2 okay (off of CD) but now when I boot I get an error message:

Unable to handle kernel paging request at virutal address c2e24154

This comes right after detecting the scsi adapter (aha152x).  It then follows with a register dump and a stack trace for insmod.

The boot completes, but now I can't mount the cd-rom drive.  Whenvever I try it gives me an error:

mount: the kernel does not recognize /dev/scd0 as a block device (maybe 'insmod driver'?)

Listing the loaded modules does show aha152x but it says "(uninitialized)" under "Used by:".  The module cannot be unloaded (it says it's busy).

Any ideas?

Thanks,

Neil.

Don't know about Redhat 4.2, but 4.1 still comes with the old modules-2.0.0 package.  Try an ugrade to modules-2.1.13, or modutils-2.1.23.  This will replace your insmod, rmmod, lsmod, and kerneld binaries.  

When I had this problem, it was because I had upgraded many many things (starting with Slackware 1.2.13 kernel) and I got it a bit out of order.  After upgrading libc, and all that goes with that, recompiling the newest modutils fixed my problems.

Interestingly enough, although modprobe -r <module> would remove an uninitialized module, like you said, rmmod <module> would do it no problem...

It means that drivers comes with RedHat works incorrectly.
You should  either install RH 4.3 with 2.0.30 kernel.
If it doesn't help. You may install 2.1.53 kernel and of
cause as a part of it upgrade your modutils.
