After trying on a 2.6.12.3 host - I wouldn't call -rc5 "stable", by just looking at the changelog *after* the release. I'm going to be *offline* so unable to handle this stuff. > The strange thing is that the same config file, same guest source but > compiled without SUBARCH (ie: regular 64-bit guest) works ok (well still > loosing memory fast - but at least it runs) > > strace ./vmlinux-2.6.12.3-bs9-x86 gives: > (...)
