Hi All,

I have just downloaded, configured, compiled and installed latest pv_ops dom0 kernel 2.6.31.5.

Linux fedora11-x86-64-host 2.6.31.5-xen-enming.teo #1 SMP Mon Nov 2 17:46:35 SGT 2009 x86_64 x86_64 x86_64 GNU/Linux

For the first time, I have used the -j4 (I am using Intel Pentium Dual Core E6300 2.8 GHz on Intel DQ45CB) argument to make.

I started the kernel build process on 2 November 2009 Monday 5:23 P.M. Singapore time.  Kernel build was completed on 2 November 2009 Monday 5:51 P.M. Singapore time. The entire kernel build process now took only 28 minutes instead of the usual 1 hour without the -jX argument.

I am happy to announce that the "net eth0: rx->offset: 0,	size: 4294967295" message does not pop up any more. I can start the ring of mpd daemons (on 2 nodes) and run mpiexec to execute MPI/parallel jobs without having to execute "ethtool -K eth0 tx off gso on" in every compute node (PV guest).

Thanks Jeremy.
