Int6 mean invalid opcode
I find same error messages
on opensuse beta with linux-2.6.24 and real hardware
http://forums.opensuse.org/archives/sf-archives/opensuse-beta/347272-updated-last-night-kernel-bug-now.html
on debian kernel under MS VirtualPC
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=463606
What version of gcc,binutils?
Could you try with distrib images to know if it could be related to your
compilation system or use a distrib kernel config to test on your compilation
system?
Instead of CONFIG_M386=y, you may try to select M486 or M586
( maybe later with tsc and mmx as cpuinfo flags line report it is supported).
