RE: [Xen-devel] need known working 64-bit upstream kernel config file for PV guest

Hi Pasi --

Thanks for the reply.  Hope your trip home went well!

Any working x86_64 config file for any upstream kernel >=2.6.32
would be fine.  I have a 32-bit config file that works fine for 2.6.27
up to 2.6.32 (and I think for 2.6.33... trying again now).

I've just found out that my config file does NOT work for x86
2.6.34-rc5 though.  Not sure why...

I've done that before but these panics are all very early and
I have a tombstone for each panic.  I thought enough people are
using upstream kernels that I must just have some CONFIG_
incorrect.  Perhaps I am wrong and I am the first one to
try these upstream kernels (at least in a PV domain)?

It seems that all the failures I am seeing have some kind
of syscall in the stacktrace and they happen early enough
in init that I suppose it is possible that this is the very
first syscall that is failing.

Thanks,
Dan
