Is anyone else seeing machines lockup with kernel-2.6.32-220? On one

to have resolved it.
Yes, the 2.6.32-220 series seems to have all sorts of issues.
Do you happen to be running an RealTek 816x ethernet chip?
I discovered the hard way that the r8169 driver in the SL6
2.6.32-220.2.1.el6.x86_64 kernel if running at 1000 Mbps caused my system
began freezing frequently after upgrading to this kernel when network
activity got high. TUV has a bug report about this already.
Installing the driver off the Realtek site seems to have solved it for now
but it was a pain to track that down.

This is a bit troublesome since most KVM virtual machines
present an RTL-series network chip to the virtual machine.
Has anyone seen trouble inside virtual machines with this kernel as yet?
