Summary: yenta_socket.c broken wireless cards.
Product: Drivers
Version: 2.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: PCMCIA
AssignedTo: linux-pcmcia@lists.infradead.org
ReportedBy: justinmatt...@gmail.com
Regression: Yes
I've sent this out to the appropriate lists, but received no response
(I don't have the time to sit and wait around for people who can figure out how
todo their jobs)
Anyways here is the patch/bisection:
I've an old dell inspiron 1200(amazingly still works), that use's
a D-Link DWL-G650, and/or a Dell Wireless 1350 for it's wireless
connection.
With using opensuse11.2(kernel:2.6.32*), the card(s) work fine, but as soon
as I pulled the latest HEAD, all hell broke loose. So after doing a
days worth of bisecting with this machine(painfully slow), it finally
came down to this commit:
commit 28ca8dd71fc170090edca62cb8129625d01b7760

pcmcia: honor saved flags in yenta_socket's I365_CSCINT register
Instead of overwriting the I365_CSCINT register, save the old value and
merely change the bits we care about.
Part 1 of a series to allow the ISA irq to be used for Cardbus devices
if the socket's PCI irq is unusable.

so after fussing around with this commit, and yenta_socket.c
I come up with something, that does get my cards
powered up, and all good(hopefully).
Anyways please have a look, if you need me to test something
different let me know.
