[Xen-devel] xen/master head PVOPS kernel 2.6.31.1 fails to load under Xen Unstable on Intel's i7 (x) X58. config, console output attached.

[Bruce Edge <bruce.edge@xxxxxxxxx>]

Does the xen/master dom0 kernel just not currrently support the i7
with x58 chipset?

The data here is obtained from an HP DL380 G6 with 2 Intel nehalem
E5540 chips. The exact same boot time hang is obtained also with a
supermicro with a single CPU and the same X58 chipset.

Serial console output and xen debug dump here:

Kernel .config is here

The current 2.6.31.1 pvops  xen/master kernel hangs when running under
Xen on a proliant the a supermicro, both X58 i7 boxes.
The Xen console is still functional but there is zero output from the
dom0 kernel.

I've tried booting with these xen versions (both of which work with a
2.6.30.3 dom0)
   http://xenbits.xensource.com/xen-unstable.hg
   http://xenbits.xensource.com/xen-3.4-testing.hg

And with the 2.6.31.1 source from both (is there a difference?)
   git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
   git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git xen/master
