[Bug 275692] Re: ath_pci must be reloaded after resume

I have read through the reports marked as duplicates of this one and see
three possibly distinct issues.

1. Have to do "ifconfig wifi0 up" after suspend
2. ath_pci needs to be reloaded after suspend; fixed by using ath5k instead
3. ath5k needs to be realoaded after suspend

The first two issues appear to be moot in Jaunty, leaving the third
issue which is exacerbated by the fact that reloading ath5k doesn't make
the Atheros card work again.

(Regarding issue #1: There is no wifi0 interface; it is now called wlan0.  After suspend it is not necessary to do a "ifconfig up" on this interface.)
(Regarding issue #2: There is no ath_pci module loaded.)

Additional information:

I have a ThinkPad X61 running Jaunty.  After suspend and resume the
Atheros card does not always work: sometimes it works, sometimes it
doesn't.  In the latter case, removing and reinserting ath5k does *not*

$ lspci |grep -i ath
