When we found the cause of NETDEV watchdog timeouts in the wireless-2.6 code,
I knew that the 2.6.18 release code would cause a serious regression.

I don't know if this is the lockup you're trying to address, but
2.6.18's bcm43xx has definitely regressed for me versus 2.6.17.x.

2.6.18 vanilla and 2.6.18 with your patch both lock my system hard
with bcm43xx. I've got an HP/Compaq nx6125 laptop. Symptoms are that
it will associate fine on its own and send traffic to/fro upon ifup,
but when I do an iwconfig, ifdown, ifup to change the access point,
the system locks (somewhat randomly) during one of those operations.
Well, the iwconfig or the ifup, actually.

I have observed similar symptoms on HPC nx6325, although I haven't managed
to get the adapter associate with an AP.

This is a PCI-E card so I need some additional patches to make the driver
detect it, and I use the firmware cut from wl_apsta.o.  The kernel is also
64-bit, 2.6.18-rc6-mm2.
