Hmm - to get fixed first compilation problem - or the second coredump crash ?

Because I need to use some combination of other kernel trees for now
I'll stay with linux git tree 2.6.25-rc8 - hopefully patches from  kvm
git tree will get there soon.

I think I'll survive the occasional crash (2x/day) caused by this
backward incompatibility.

As compared with kvm-64  I no longer experience sudden  qemu-kvm stops,
which I had to resolve by attaching strace to qemu procees - that
magically 'unfreezed' qemu
and it was happening quite often.
