Hmmm, I deleted all my 2.6.16 kernels and I can't test a newly compiled 2.6.16 kernel before the weekend. But if I remember correctly, on previous kernel versions skype just generates 100% system load when using the sound device after some time (especially after a resume) and stuttered audio but no system lockups. Hence, it worked much better than now from the kernel point of view but was not usable from the skype users point of view. It was a userspace only problem. regards, J?rg - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
