Kernel debugging

I have a USB audio device (Yamaha Audiogram 6) that no longer works with my 3.8.7 kernel, but used to in an older 3.X kernel (not sure which).

I'm trying to downgrade to an older kernel in an effort to track down which change(s) may have broken it.  I am presently using linux-bfs from AUR (3.8.7) -- is there somewhere I can get an older linux-bfs AUR package?

Or should I just build a kernel the traditional way?

Re: Kernel debugging

Old official Arch packages are here http://arm.konnichi.com/

For getting a older version of AUR packages you will have to mail the package maintainer, I guess.

Re: Kernel debugging

Since BFS patches shouldn't touch sound drivers, it's likely that this bug comes from upstream.

To find out which commit introduced problem in vanilla kernel, run git bisect on:
