Created attachment 403252 [details] Output of emerge --info Several latest revisions of QEMU crash when Ctrl+Alt+U is pressed at SDL window. This is a known bug (https://bugs.launchpad.net/qemu/+bug/1412098) and the workaround is known, so Gentoo can at least ship QEMU with this patch. This bug doesn't depend on the guest OS (it happens even without such OS) and I guess it doesn't depend on arch. This is the command line which I use to run QEMU, as reported by AQEMU: /usr/bin/qemu-system-x86_64 -monitor stdio -vga std -enable-kvm -m 2048 -localtime -cdrom <some image> -hda <some other image> -boot once=d,menu=off -net nic,vlan=0 -net user,vlan=0 -name <something> Known not affected versions : app-emulation/qemu-2.1.x (disappeared from Portage) app-emulation/qemu-2.3.0-r1 (~amd64 keyword) Known affected versions (currently stable for "amd64"): app-emulation/qemu-2.2.0 app-emulation/qemu-2.2.1-r2 Build variables for the latter: USE="aio alsa caps curl fdt filecaps jpeg ncurses nls opengl pin-upstream-blobs png python sdl seccomp threads usb uuid vhost-net -accessibility -bluetooth -debug (-glusterfs) -gtk -infiniband -iscsi -lzo -nfs -numa -pulseaudio -rbd -sasl (-selinux) -smartcard -snappy -spice -ssh -static -static-softmmu -static-user -systemtap -tci {-test} -tls -usbredir -vde -virtfs -vnc -xattr -xen -xfs" PYTHON_TARGETS="python2_7" QEMU_SOFTMMU_TARGETS="i386 x86_64 -aarch64 -alpha -arm -cris -lm32 -m68k -microblaze -microblazeel -mips -mips64 -mips64el -mipsel -moxie -or32 -ppc -ppc64 -ppcemb -s390x -sh4 -sh4eb -sparc -sparc64 -unicore32 -xtensa -xtensaeb" QEMU_USER_TARGETS="i386 x86_64 -aarch64 -alpha -arm -armeb -cris -m68k -microblaze -microblazeel -mips -mips64 -mips64el -mipsel -mipsn32 -mipsn32el -or32 -ppc -ppc64 -ppc64abi32 -s390x -sh4 -sh4eb -sparc -sparc32plus -sparc64 -unicore32"
if the fix is already in 2.3.0, then there's nothing for us to do
