   I wonder if you could help me squash a bug in the tcp code. 
   Here is what we know thus far:
   
   An SMP (x386 dual) 2.4.17 kernel crashes with an attempt to
   deference NULL at the end of tcp_fragment() (in
   net/ipv4/tcp_output.c) while attempting to link in the newly
   created fragment.  
   The bugzilla report is:

%99 of all such bug reports turn out to be driver bugs
where the net driver frees SKBs improperly or there is some
missing internal locking in the net device driver.

I think you efforts are better spent auditing what net
drivers are being used on this machine :-)
