[Bug 502433] Re: Lucid: b43 fatal DMA error on Dell Mini 9

I applied the patch at http://patchwork.kernel.org/patch/66372/ to the
ubuntu_kernel branch. It doesn't apply cleanly, so I had to manually
apply a few of the changes. After rebooting into the new kernel, I'm
still having problems, I can try to connect, but the syslog just keeps
filling up with the following message which echos every few hundred
milliseconds.

b43-phy0 ERROR: MAC suspend failed

This appears to happen only after I try to connect to a WPA-PEAP
encrypted network. I can connect to an insecure access point without any
problems, provided I haven't attempted the WPA connection since wireless
networking was last enabled. Attached is the diff generated by git, for
anyone who wants to work on debugging this.
