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.
