The last update we have from VMware is that the fix will be in 6.0p3/5.5p8 - both of which are targeted for a mid year release.

That's on VMWare, right? Jason has seen the same issue:

 http://marc.info/?l=linux-kernel&m=145280623530135&w=2
 http://marc.info/?l=linux-kernel&m=145523785705624&w=2

 "Works fine on real hardware and KVM. Filed an issue with VMware and the fix

Jason, what's the state of this?

Thanks,
