VM86 Syscall Kernel Panic http://packetstormsecurity.com/files/124620/Virtual86SwitchToEmmsFault.c
This program maps memory pages to the low range above 64k to avoid conflicts with /proc/sys/vm/mmap_min_addr and then triggers the virtual-86 mode. Due to unhandled FPU errors, task switch will fail afterwards, kernel will attempt to kill other tasks when switching.
