Thanks for the reply.
You appear to be correct, I re-installed Lenny with the 486 kernel, grub, and
desktop and it re-booted without fail 18 times. I added the 686 kernel after
the 16th re-boot then re-booted OK with the 486 kernel. The next re-boot
failed as before using the 686 kernel, then another re-boot with the 486
kernel was fine. I dumped the entire /var/log to disc after the first, 16th,
and 18th 486 re-boot, I have not yet found any obvious information from any
log giving details of a crash, where should I look? The only information
appears to relate to successful 486 boots.
