Talking of which, the git tree has now been updated with the latest to correlate with 404 as closely as possible.
That's what I actually meant sorry. Could you please make a .deb of that BFS kernel?

Ok, here you go:

Modules deb (required by all of the below)

Multiboot deb

U-boot uImage
Also requires "dummy" kernel-bfs package, see attached

Standard kernel and flasher deb

Headers deb for compiling fcam-drivers on scratchbox, etc
Also requires "dummy" kernel-bfs package, see attached

UPDATED LINKS with watchdog re-enabled - please let me know if there are any problems.

Attached are fcam-drivers for BFS6.

The pulseaudio package didn't resolve distortion, neither did disabling the scheduler reset fork patch on my quick build.

Re: BFS for the power kernel
 
Hmm, that's a real shame. I've still had no distortion so far (other than very slight during the "ringing" phase of a call on an odd occasion). Have you tried setting swappiness to 0? I've also got some schedtool settings:

Code:
schedtool -I `pidof hildon-desktop`
schedtool -I `pidof hildon-status-menu`
schedtool -D `pidof trackerd`
schedtool -D `pidof tracker-indexer`
schedtool -F -p 99 `pidof Xorg`
schedtool -I `pidof mafw-dbus-wrapper`
schedtool -R -p 5 `pidof pulseaudio`
.. and a few of the tunables from this thread, although I have nr_requests as 32, page-cluster as default of 5, and swappiness 0 as mentioned.

I have similar scheduling on boot as well as I/O tuning settings. It may have been bumping CONFIG_HZ to 300, so I'll see what that does.

I've updated the links with watchdog re-enabled. Please let me know if it works.

.. and by popular request ;), here are the bleeding-edge wireless modules

Re: BFS for the power kernel
 
The newest kernel package without WATCHDOG=n works fine. My *just compiled* fcam-drivers don't work with your kernel,

Wanna toss those up?

EDIT: Still have distortion. Set swappiness to 0 and it seems (?) to have gone away, but it was always too random to predict.

Re: BFS for the power kernel
 
Thanks a lot Tigerite... will give this a shot right now.
