Hello,
I have applied the patches that Sujith posted last night with the latest 
compat drivers and my HTC now works without issues.
I have also loaded it with 6 more stations and it worked fine for a 
while but after a few minutes I got a kernel trace.
The system is an IBM T61 with Fedora14 i386 and the latest packages.
Trace bellow:
