From: Justin P. Mattock on 19 May 2010 17:10 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 Author: Jens K<C3><BC>nzer <Jens.Kuenzer(a)fpga.homeip.net> Date: Sat Mar 6 07:46:16 2010 +0100 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.

Anyways please have a look, if you need me to test something different let me know. Signed-off-by: Justin P.
