Summary: Box locks up hard when setting ip address RH9 and DWL650+

Initial Comment:
 I have a DWL650+ running on a laptop with RH9. The 
access point is a DI614+. The driver installs OK and I 
can issue iwconfig commands. Driver version is 0.2pre5

Eg iwconfig wlan0 mode Managed rate 22M channel 6 
key 'whatever the key is' essid Preston

After I have done this I issue an ifconfig wlan0 
192.168.0.50 netmask 255.255.255.0 at which point the 
system locks up and can only be switched off and 
rebooted.

The log is below.

I have a desktop system running RH9 with a DWL520+ 
which works fine but I am at a loss with this. Any help 
would be appreciated.

Thanks

Feel free to use e.g. pre6_plus_fixes_6 tar, this will fix
our locking, at least temporarily.

Problem seems to happen because of nested spin_lock_irqsave()s
(didn't know that this is an evil thing to do - I assumed it
just increases the refcount when same process).
A fix is in the works, should be fixed in pre7.

Have tried pre6_plus_fixes and get the same lock up when 
setting ifconfig.

The debug level was set to 0x0f. Log is below.

This is due to locking issues causing the box to lock up.
Please report about pre6_plus_fixes
