Madwifi 0.9.3.3 locks kernel when creating a VAP in ap mode.

Description

After I upgraded from madwifi 0.9.3.2 to 0.9.3.3 my kernel freezes when I try to create a VAP in ap mode. Just loading the modules works fine, and the creation of a VAP in sta mode also works (I could no test it, because I don't have another access point).

I've observed this behavior in kernel 2.6.22.9 and 2.6.23.1, both as packaged and patched for Fedora 7 (kernel-2.6.22.9-91.fc7 and kernel-2.6.23.1-10.fc7). With kernel 2.6.22.9, madwifi 0.9.3.2 worked without a problem.

The good news is, I've upgraded to a package from ATrpms from subversion 2756 and it worked again with kernel 2.6.22.9. I could not test with kernel 2.6.23.1 because the isn't a package available for this kernel yet.

Maybe a new release from the trunk is in order...

For the record. Version that freezes:

ath_hal: 0.9.18.0 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413)
wlan: 0.8.4.2 (0.9.3.3)
ath_pci: 0.9.4.5 (0.9.3.3)
ath_rate_sample: 1.2 (0.9.3.3)
wifi0: Atheros 5212: mem=0x50000000, irq=21

Version that works:

ath_hal: 0.9.30.13 (AR5210, AR5211, AR5212, AR5416, RF5111, RF5112, RF2413, RF5413, RF2133)
wlan: 0.8.4.2 (0.9.4)
ath_pci: 0.9.4.5 (0.9.4)
ath_rate_sample: 1.2 (0.9.4)
wifi0: Atheros 5212: mem=0x50000000, irq=21

And here is my modprobe.d/madwifi file:

alias wifi0 ath_pci
alias ath0 ath_pci
options ath_pci autocreate=ap

The problem is still present with madwifi 0.9.4.

My current kernel is 2.6.23.15 for Fedora 8 (2.6.23.15-137.fc8). The subversion 2756 still works, however.
