I'm afraid non of your debug output made it out however. I thought it was because it just wasn't getting that far but looking at the 250Hz log I don't see any there either??? The patch applied (with fuz) to both kernel sources and I built/installed them from clean. I don't find any messages starting with "hpet:" in either trace???
