Well, you could try booting the kernel that works and running "lsmod" to see 
which modules are included.  Then turn off all other modules and build a new 
kernel -- see if that kernel still boots properly.

I believe I read somewhere that the TS config files don't have all of the 
dependencies 100% correct so you likely just turned something off that didn't 
have a dependency properly set.  Because you're using modules, the dependencies 
can't be determined until run time.  If you built a monolithic kernel instead 
you'd get linker errors (that might be a good way to test this).

It's also possible that the initrd is just messed up and won't boot the trimmed 
down kernel for some reason.  But I'm not intimately familiar with the mkinitrd 
procedure for these embedded boards.  (I know RHEL uses a fairly sophisticated 
mkinitrd script that queries a bunch of system settings to determine what to 
put into the initrd.)

(PS:  Note how I've trimmed extraneous information from this message?  You can 
do that too.  It's called "highlight-and-Delete". ;-)
