I finally built and installed this today. It turns out that one more patch is needed to avoid dmesg errors like this:
[ 206.631936] ------------[ cut here ]------------

This would be followed by a dump of registers and a stack trace. Everything would appear to work despite this. When I was running an earlier build without that patch, there we a few messages like this within the first 15 minutes and nothing in the subsequent days.
