Do these options work with the F11 guest kernel (2.6.30) as well?

Are these going to be in 5.4?

I'm running 2.6.18-164.11.1.el5xen and the fedora kernels for F11 and F12
are not very stable for me.  Dom0 is a Centos 5.4 2.6.18-164.9.1.el5xen

These fedora kernels seem to lockup (processes get stuck in D state)
whenever put under any load:


Yes, I tried a fedora 11 kernel on a fedora 12 system. This is the most
stable for me.

Here are some bugzilla entries (one posted by me) that point to this

kernel 2.6.31 processes lock up in D state

FC12 hangs under heavy disk I/O

Any help appreciated.
