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: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
