OUch. "So on sane kernels" I guess RT isn't sane then!

Yea that performance hit is a nuisance, although in reality when I
really need RT I wont be doing much over a VPN... so I may have to suck
up to rebooting between kernels for a while. No big deal.

Thanks again - I will test that new patch later.
