Please don't post into unrelated threads. Anyway, all your crashes share one thing, before the crash UML did a sigsuspend(). It does only so in the SIGWINCH irq path. To verify ma theory please apply the attached patch. It disables the feature that you can resize an UML window on the host side and UML will change the terminal size in the guest. Thanks, //richard
