Are you scanning for the read-port? If so, you can confuse some
ISA cards, notably NE2000 clones. I can freeze my machine about
one time in three this way, with various messages during the
death throes. However, this seems independent of kernel version
to me (others may tell me I am wrong, though).

I can post you some patches for isapnptools-1.11 that will help narrow
down read-port clashes, if that is your problem....
