The one that came with kernel-source-2.4.18 right?  Most (if not all)
of the symptoms you described can be traced to device access ...

The ONLY reference to devfs on that page reads:

  Note: If you use devfs you may need to make the device: mknod
        /dev/hdb b 3 64

and it is in regards to getting CDRW/DVD working.  This is not nearly
enough to get devfs to work.  I completely agree with Derek's advice:
rip out devfs, see if that fixes things (it likely will if your system
hasn't been hosed by reckless devfs use) and only once things are back
in order contemplate adding devfs again.

Do yourself a favour and read that README, make sure you understand it
(not sure I do myself and haven't had the time to test that), do as it
tells you to and only then try a devfs enabled kernel.
