Hi guys,  If I do a 'rmmod eeepc-laptop', while connected to my AP, I get the following error messages from ath5k: ath5k phy0: noise floor calibration timeout (2417MHz) ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: can't reset hardware (-5) ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: can't reset hardware (-5) wlan0: No ProbeResp from current AP 00:1d:0f:e9:c7:c0 - assume out of range ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: ath5k_chan_set: unable to reset channel (2412 Mhz) wlan0: failed to set freq to 2412 MHz for scan ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: ath5k_chan_set: unable to reset channel (2417 Mhz) wlan0: failed to set freq to 2417 MHz for scan ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: ath5k_chan_set: unable to reset channel (2422 Mhz) wlan0: failed to set freq to 2422 MHz for scan ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: ath5k_chan_set: unable to reset channel (2427 Mhz) wlan0: failed to set freq to 2427 MHz for scan ath5k phy0: failed to wakeup the MAC Chip ath5k phy0: ath5k_chan_set: unable to reset channel (2432 Mhz) wlan0: failed to set freq to 2432 MHz for scan wlan0: failed to set freq to 2437 MHz for scan wlan0: failed to set freq to 2442 MHz for scan wlan0: failed to set freq to 2447 MHz for scan wlan0: failed to set freq to 2452 MHz for scan wlan0: failed to set freq to 2457 MHz for scan wlan0: failed to set freq to 2462 MHz for scan wlan0: failed to set freq to 2467 MHz for scan wlan0: failed to set freq to 2472 MHz for scan wlan0: failed to set freq to 2484 MHz for scan wlan0: failed to restore operational channel after scan wlan0: authenticate with AP 00:1d:0f:e9:c7:c0 wlan0: authenticate with AP 00:1d:0f:e9:c7:c0 wlan0: authenticate with AP 00:1d:0f:e9:c7:c0 wlan0: authentication with AP 00:1d:0f:e9:c7:c0 timed out  Then I lost my wireless connection.  I'm running latest Linus git tree (2.6.28-rc2) on a Eeepc 701.  The problem doesn't happen on 2.6.27.4, but as 2.6.28-rc1 doesn't boot on this machine, it would be a bit difficult to bisect it.  Thanks.

The trick with bisection is to identify the fix, use git cherry-pick to apply it before testing, and then git reset

Matthew: I nagged you twice about different consequences of this commit, so here's a third .  You said rfkill no longer automatically frobs on suspend/resume, which was what I was worried about last time.   Should the core code also be modified so it doesn't do anything when the rfkill device is unregistered? I think there's definitely an argument in favour of that, though I suspect that's a design feature - if you remove the control mechanism for a radio, the safe state for that radio to be in is not transmitting.

After this does ath_info work ?

It says: MAC revision 0xffff is not supported!  And I have realized that I get a flood of 'failed to wakeup' and 'can't reset the hardware' error messages, just some seconds after the eeepc-laptop module removal.

 No, it doesn't. It says: MAC revision 0xffff is not supported!  And I have realized that I get a flood of 'failed to wakeup' and 'can't reset the hardware' error messages, just some seconds after the eeepc-laptop module removal. Well it seems that during module removal, card gets no power at all. I don't see any reason for this behaviour. Do you have pci-e hotplug enabled ?
