unfortunately have no idea
One question. What are the issues with the current 3.8.13 which are fixed in version you are trying to build?
I don't know if it fixes anything. But you know my main interest in the raspberry is to use it as a small audio player as a replacement of a Squeezebox player.
So often it is used together with a USB-DAC. Personally I have no problem with the current piCorePlayer with the USB-DAC that I use, but I get reports that some USB-DACs still produce a cracklling noise from time to time from other users.
It is amassing, but there are more than 200 downloads of the piCorePlayer
My previous piCorePlayer was based on linux 3.8.12 - and there were some problems that were mostly solved by changing to the fiq_split fix version (3.8.12 based).
Then came the 3.8.13 version which was much better than the 3.8.12 version - but recently the fiq_split branch also have been updated to 3.8.13, and even one more change has been done in the USB-handling in this branch which is not present in the "pure" 3.8.13 linux.
Therefore I thought that this version might be even better than the "pure" 3.8.13 linux - and wanted to give it a try. But unfortunately I can't compile a new fiq_split 3.8.13 kernel.
And I thought that I finally could manage to build new kernels (I did make a 3.8.12 and a fig_split version based on 3.8.12).
