FWIW, when I ltrace the stuck kvm process, I get an endless string of memcpy(0x7fffb09355f0, "\224\213'\206", 4) (the value changes from run to run, but stays constant within a run) Unfortunately Debian packages don't seem to be built with debugging symbols, so gdb doesn't show a very enlightening backtrace. I'll try to get more info. - R.
