atheros (ath_pci) wireless fails to recover after suspend.

[jcdutton]

Regression.
Wireless recovered after suspend correctly in "Hardy", but fails now under "Intrepid".

This manual command as root recovers from the problem if run after each resume from suspend.

ifconfig wifi0 up

And here also. This is on a Thinkpad T60p with an Atheros AN5212. Incidentally, the AN5212 appears to be unsupported by the ath5k module, even though it claims it, meaning that I had to blacklist the Ath5k module so I could run with ath_pci to get any wireless working at all.

Seems to be a duplicate of #275692

[Thomas Schewe (thosch66)]

It's a duplicate of <a href="https://bugs.launchpad.net/bugs/272300">#272300</a>.

It looks like there is another workaround than removing/reloading the kernel-modul. The interface wifi0 is missing after resume. After configuring this interface by

ifconfig wifi0 up

networt-manager can reconnect (ya href="https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules/+bug/272300/comments/16">see comment #16 on bug #272300</a>.
