>Description:
awi driver worked very happy during last IETF meeting period,
but now it does not work correctly when accessing the card
with memory mapped i/o. access via i/o port works fine.
kernel printf shows the following repeatedly and goes into
infinite loop:
awi0: no command in progress?
awi0: set_infra failed (card unhappy?); erroffset 0
awi0: reset
it looks to be some problem in the change into i82365*.c,
since awi*.c was not changed much since last IETF (Nov 1999).
>How-To-Repeat:
give enough memory window to pcic0, put awi card and bring it up.
>Fix:
temporary workaround is to disable memory mapped access mode.
