Please disable it and try again. Your assumption was correct, disabling the group scheduler has fixed all the problems (except for the fact that when xruns do occur the values are still extremely large - but that's probably just version incompatibility between ALSA drivers in the kernel and libasound). Of course this suggests that the group scheduler is still borked, at least on amd64. Thanks for your help!
