I've been using qemu using the Linux framebuffer console, on a machine that's a bit too slow to support X. There have been more than a few snags, but perhaps the most irritating one was that if qemu crashed (and received a SIGSEGV), it would leave the console in an unusable state. This would require me to log into the machine via ssh and reboot it remotely. I'm submitting a patch that installs a signal handler to call sdl_cleanup(), then exit. This has alleviated my problem with the system being left in an unusable state, however I suspect that the segfault problem lies somewhere in SDL itself, and not in qemu.
