Another good option if everything else fails (and you have configured previously kernel.sysrq=1 with sysctl) is:
Alt+SysRq+ {R, E, I, S, U, B}
Would you expect this to work with USB keyboards? There's more protocols in the way of USB than PS/2, or other schemes, requiring a working operating system
i would not only expect, it works for sure
ALT+PrintScrn+S

Under graphical environments (such as GNOME or KDE) 'Alt'+'PrintScrn/SysRq'+key combination generally only leads to a screenshot being dumped. To avoid this Print Screen feature the magic SysRq combination should include the Ctrl, becoming 'Ctrl'+'Alt'+'SysRq'+key. For the same purposes the AltGr key, if present, can be used in place of the Alt key. On some laptops SysRq is accessible only by pressing 'Fn'. In this case the combination is a bit trickier: hold 'Alt', hold 'Fn', hold 'SysRq', release 'Fn', press key. The magic SysRq can also be accessed from the serial console.[2]
