If you don't want to go back into wireless-2.6 git to do that I can send you my known working copy (for rt73 and I hope for rt61) of compat-wireless-2.6 which will compile under 2.6.24. However it is just over 1MB in size so I won't sent it to you unless you would like me to do that instead of you pulling git from wireless-2.6 for mid January (actually the most recent working version would be immediately before the patch which raised the version of rt2x00 to 2.1.0).

Here's some further information. I have a fully functioning version of rt2x00-2.0.14 and mac80211 from wireless-2.6/compat-wireless-2.6 of mid January which works fine on kernel 2.6.24. On doing a comparison with the rt2x00 in vanilla kernel 2.6.25-rc2, there are no material differences. (There was a slight change in the declaration a variable in rt2x00usb.c but it is immaterial.) I compiled up the working mid-January version of rt2x00 and mac80211 under kernel 2.6.25-rc2 and I get exactly the same result as I reported earlier, namely I get a kernel panic as soon as I try to associate. It looks therefore as if something has changed within the remainder of the kernel which has caused rt2x00 (and possibly mac80211?) to break. This probably explains the problem another user reported with rt61.

The patch applied OK (with some offsets as you say) but it doesn't help. The kernel panic still occurs when association is attempted.

I have an idea, could you try below patch? Note that while applying it will mention something about a line offset, but that can be ignored. This could perhaps also fix the TX/RX issue mentioned earlier in the thread, but I am not quite sure about that. --- diff --git a/drivers/net/wireless/rt2x00/rt2400pci.c b/drivers/net/wireless/rt2x00/rt2400pci.c index b63bc66..460ef2f 100644 --- a/drivers/net/wireless/rt2x00/rt2400pci.c +++ b/drivers/net/wireless/rt2x00/rt2400pci.c @@ -953,8 +953,12 @@ static int rt2400pci_set_device_state(struct rt2x00_dev *rt2x00dev, rt2400pci_disable_radio(rt2x00dev); break; case STATE_RADIO_RX_ON: + case STATE_RADIO_RX_ON_LINK: + rt2400pci_toggle_rx(rt2x00dev, STATE_RADIO_RX_ON); + break; case STATE_RADIO_RX_OFF: - rt2400pci_toggle_rx(rt2x00dev, state); + case STATE_RADIO_RX_OFF_LINK: + rt2400pci_toggle_rx(rt2x00dev, STATE_RADIO_RX_OFF); break; case STATE_DEEP_SLEEP: case STATE_SLEEP: diff --git a/drivers/net/wireless/rt2x00/rt2500pci.c b/drivers/net/wireless/rt2x00/rt2500pci.c index add8aff..ffcd996 100644 --- a/drivers/net/wireless/rt2x00/rt2500pci.c +++ b/drivers/net/wireless/rt2x00/rt2500pci.c @@ -1106,8 +1106,12 @@ static int rt2500pci_set_device_state(struct rt2x00_dev *rt2x00dev, rt2500pci_disable_radio(rt2x00dev); break; case STATE_RADIO_RX_ON: + case STATE_RADIO_RX_ON_LINK: + rt2500pci_toggle_rx(rt2x00dev, STATE_RADIO_RX_ON); + break; case STATE_RADIO_RX_OFF: - rt2500pci_toggle_rx(rt2x00dev, state); + case STATE_RADIO_RX_OFF_LINK: + rt2500pci_toggle_rx(rt2x00dev, STATE_RADIO_RX_OFF); break; case STATE_DEEP_SLEEP: case STATE_SLEEP: diff --git a/drivers/net/wireless/rt2x00/rt2500usb.c b/drivers/net/wireless/rt2x00/rt2500usb.c index d9643c5..9f59db9 100644 --- a/drivers/net/wireless/rt2x00/rt2500usb.c +++ b/drivers/net/wireless/rt2x00/rt2500usb.c @@ -996,8 +996,12 @@ static int rt2500usb_set_device_state(struct rt2x00_dev *rt2x00dev, rt2500usb_disable_radio(rt2x00dev); break; case STATE_RADIO_RX_ON: + case STATE_RADIO_RX_ON_LINK: + rt2500usb_toggle_rx(rt2x00dev, STATE_RADIO_RX_ON); + break; case STATE_RADIO_RX_OFF: - rt2500usb_toggle_rx(rt2x00dev, state); + case STATE_RADIO_RX_OFF_LINK: + rt2500usb_toggle_rx(rt2x00dev, STATE_RADIO_RX_OFF); break; case STATE_DEEP_SLEEP: case STATE_SLEE

I did that yesterday and it just reported a kernel panic on the terminal with the message: Kernel panic - not syncing: Aiee, killing interrupt handler! There is a complete lock up. Even the two leds don't send a dump in morse code (if that is still a feature of the 2.6 kernels). They just flash together at 1 second intervals. However, I do not have debugging enabled on 2.6.25-rc2 (I was just interested to see how it worked). If it is thought to be useful I can recompile the kernel with debugging enabled, but this should be reproducible by anyone with a rt73 stick. By way of a further data point, I can scan OK using 2.6.25-rc2 and it will report all the available access points in my area. But as soon as association is attempted, it blows up.

The modules load when I plug the stick in but I then get a complete kernel lock up with two flashing leds. Nothing is recorded to system logs. The last logged messages are that usbcore has registered new interface driver rt73usb, and that the rate control algorithm has been selected on phy0. This happens whether the simple or pid mac80211 rate control algorithms have been chosen. This is a shame because 2.0.14 was working really well for me until the mac80211 changes 2 or 3 weeks ago broke it. (Shortly followed by the release of 2.1.*).
