Description

XO-1.75 recorded audio is complete gibberish in os6. One may also hear wierd noises out of the speakers when starting/ending the recording process in the Record activity.

This is a regression to the 20120926.1806.olpc.6d0e853 kernel included with os5. Installing this kernel on os6 makes the recorded audio intelligible again (but not perfect).

Reverting commit f9d35acbe063de67747826ddba2bcaa692757e1b. (enable cache speedup) does not help. Needs a bit more investigation.

We were close. The commit that introduces the regression is a8137cd10a1ab06650a337c85b001cb4dba3a56d "ARM: pxa: append options of tauros2 L2 controller"

It even introduces the regression before we've explicitly turned it on on the .config (f9d35acbe063de67747826ddba2bcaa692757e1b).

Reverted those 2 commits for the time being, because I know Jon has other priorities. We could consider a fix for this (that doesn't involve reverting the speedup) if it arrives within the current release milestone, i.e. before Nov 15th.
