Last week i was playing with my old linux 2.0.36 i486 box, while i was playing with the command ping and trying combinations of commands i found that when u do a ping -s 65468 -R ANYIPADDRESS ( -R record route) the system starts to print on the screen kernel dumps , freezes complitely and after few secconds the system reboots. The major problem with this (if this is a bug, because i dont have time to install differents kernels and test it better) is that command can be run by everyone because you dont need root permissions to make a -R. I tested this on a 2.0.35 and .36 (both slackware), when u try to do this on a 2.2.x the system prints out "message too long". I think the problem is that there is a size-check missed when u reach the maximun packet size and u put the route information, but anyway i am not a guru on kernels.
Being no guru I noticed there were some patches for these kernels and 2.0.x kernels now run into 2.0.38 so I suggest you test 2.0.38 before you yell BUG. Browsing the info on http://www.kernelnotes.org/ does at least make one wonder wether this is a known issue that's solved as there are changes in the networking code.
