ath5k module does not properly restart after suspend

[kozimodo]

In order to resume wifi, ath5k and all related modules must be removed and then ath5k must be reloaded. This was not a problem with the backports module in Jaunty.

[This is an automated message. Apologies if it has reached you inappropriately.]

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue.

If this bug really is a bug in the linux-meta package you can move it back to linux-meta and set the Status to Confirmed, or contact us on the #ubuntu-kernel channel on the FreeNode IRC server. Thanks.

Same problem here. I'm going to confirm this. It seems to be specific with the ath5k driver in the backports-modules package.

03:00.0 Ethernet controller: Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)
 Subsystem: Netgear Device 5b00
 Flags: bus master, medium devsel, latency 168, IRQ 11
 Memory at f4000000 (32-bit, non-prefetchable) [size=64K]
 Capabilities: <access denied>
 Kernel driver in use: ath5k
 Kernel modules: ath5k

Still broken with latest backports-modules.

seems I have got the same issue here.
ath5k is used on my karmic (upgraded few hours ago from jaunty).
00:09.0 Ethernet controller: Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01)

wifi works fine at startup, but then it fails and I can't get it working as soon as I suspend and resume from suspend. (rmmod / modprobe ath5k/ath won't fix)

I might have noticed a clue though :

dmesg | grep ath gives me this before suspend :
[ 12.713661] ath5k 0000:00:09.0: enabling device (0000 -> 0002)
[ 12.713677] ath5k 0000:00:09.0: PCI INT A -> Link[LNK3] -> GSI 11 (level, low) -> IRQ 11
[ 12.713764] ath5k 0000:00:09.0: registered as 'phy0'
[ 12.818313] ath: EEPROM regdomain: 0x30
[ 12.818318] ath: EEPROM indicates we should expect a direct regpair map
[ 12.818322] ath: Country alpha2 being used: AM
[ 12.818324] ath: Regpair used: 0x30
[ 14.440610] ath5k phy0: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43)
[ 14.440614] ath5k phy0: RF2112B 2GHz radio found (0x46)

and that *after* suspend :
[ 115.784403] ath5k 0000:00:09.0: PCI INT A disabled
[ 121.703339] ath5k 0000:00:09.0: PCI INT A -> Link[LNK3] -> GSI 11 (level, low) -> IRQ 11
[ 121.703427] ath5k 0000:00:09.0: registered as 'phy0'
[ 121.805448] ath: EEPROM regdomain: 0x30
[ 121.805453] ath: EEPROM indicates we should expect a direct regpair map
[ 121.805457] ath: Country alpha2 being used: AM
[ 121.805459] ath: Regpair used: 0x30

the diff is
before = ath5k 0000:00:09.0: enabling device (0000 -> 0002)
after = ath5k 0000:00:09.0: PCI INT A disabled

disabled sounds bad to me but i'm no dev at all :)
hope this helps
