ath5k issue on Dell Latitude e6500

[Eric Sheesley <esheesle@shadowlair.com>]

I recently installed Debian on my new Dell latitude e6500.  I tried a 64
bit install to start with, and most things worked well but every 1-2
hours my network would fail.

I have an Orinoco 802.11 b/g pcmcia card and have a WPA secured network.
 After reading around a bit, I found several posts mentioning that the
64bit kernel and wpa_supplicant had some issues.

Instead of trying for the next several weeks to get it working, I
decided to reinstall with a 32bit OS using the bigmem kernel.  I also
liked the idea of having flash and java support so this wasn't just one
more reason to go back to 32 bit.

I got the 32 bit version of Debian installed and the wireless card
worked great(not positive the 1-2 hour issue still isn't valid but find
out shortly if it is).  I installed the bigmem kernel, rebooted, and
ath5k now reports an error.  The output of the working vs non working
kernel ath5k follows.

working 32bit(no bigmem):

0000:04:00.0 failed with error -110



I have the same kernel versions for both kernels so am very confused by
this.  Any help would be greatly appreciated.

Thanks,
Eric
