Panic is the only thing that calls smp_send_stop, so I think the badness
has already happened.

Ryan: is this an SMP guest?

Try "maxcpus=1"

I added it a couple of days ago.

Thanks,

The config option will probably be removed at some point. It's just
there to aid debugging in case someone reported block dev problems.

In the *unstable* series you really shouldn't be relying on
compatibility between different versions of the tools, xen, or the
kernels. You should always install a complete set of binaries. In the
unstable series we reserve the right to change interfaces, and
frequently do. 

Best,
Ian

OK, that's news to us - we haven't seen any problems.

It's been tested with dd's and kernel builds, and wasn't expected to be
a particularly dangerous change.

How you confirmed that disabling the option fixes your problems? Can you
give a simple recipe to provoke problems?

It doesn't seem to be destablizing, at least for us. Possibly there's
been some feature interaction with later checkins. 

Anyone using the unstable tree should be reading the changelog
closely...
