>Organization:
TDK Semiconductor
>Environment:

PC with Emerging Technologies ET/5025-16 ISA card installed.

>Description:

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.

>Fix:
