Description Don Lewis 2000-03-03 11:00:02 UTC

If an Emerging Technologies ET/5025-16 ISA card is installed, ex_isa_identify()
hangs the machine when it accesses the I/O ports used by the ET card.  It
appears that ex_isa_identify() hangs when it executes look_for_card().
Apparently the code in ex_isa_identify() provokes the ET card into yanking
IOCHRDY low forever.

This has probably been broken since if_ex.c 1.24.

How-To-Repeat: 
Attempt to boot the GENERIC kernel with an ET/5025-16 card installed.

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?
