Scanning through the BNC, I don't see any reason to consider changing the long used preemption model. It looks to me like something simply went broke recently (as things occasionally do), and that something needs to be hunted down and fixed up.
OTOH, originally CONFIG_PREEMPT was taken exactly for a better desktop usage, and now this showed failing. Moreover, other major distros use PREEMPT_VOLUNTARY. So, overall, this shouldn't be seen as a "fix", but it's a good timing for switching, IMO.
I personally prefer (and use) VOLUNTARY due to its better throughput, and have no issue with it being selected in general. It's only the "this change fixes something" aspect that causes me serious concern. Note: the change will impact realtime latencies, so there's some potential for regression reports, though unlikely. -Mike -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
