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,
Jörg
