FWIW

Dual P-II w/ 128 MB of memory.  pre7-2 and pre7-3 (with #error removed)
both boot up and let me login ok -- I have an NFS automounted home dir. 
But... doing a lot of "netscaping" -- clicking around, opening new
windows, making the machine do lots of mmap() and swap -- causes the box
to lock hard.

I'm gonna hook up a serial console and see if I can get output.  Might
try booting w/ CONFIG_SMP/num-cpus==1 to see if that triggers any ugly
behavior too.

I'll also try to reproduce the problem without NFS in the picture.
