Hi Jeremy,
hi all,

I have checked out Jeremy's last git built of dom0 pv_ops kernel

commit 41a85de5caef68bbd58e11ed7b781b7867d96eaa
Merge: 62bf426... 0ee0f94...
Author: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>

I have set up on a Dell PE1950 2xDualXeon 5130 an LVM2 partition
containing XFS. I have built Jeremy's kernel successfully, so the
running dom0 Kernel is the one mentioned above.
System is Debian-Lenny, Xen and Xen-tools are self-built.

If I make some I/O, eg:
cd linux-2.6-xen-git (which is then on the lv with the XFS filesystem)
make -j 7 ; make install; make -j 7 modules; make modules_install

in dmesg appears a kernel trace after a while. But compiling continues
and all keeps up and running. This only happens if the kernel is running
under xen 4.0.2-rc1-pre hypervisor. Nothing strange happens if I run it
on bare-metal (same machine) without hypervisor.
I have not tested bonnie or iozone yet.

I have attached booting output of xen 4.0.2-rc1-pre
as well as the trace (file console-kerneltrace.txt).
Kernel config is also attached (config-

Perhaps you can help. Please let me know if I have forgotten any
important information.

Many thanks and best regards,
Ulf Kreutzberg
