No, I did not press all three keys at the same time. The posting I
saved says, "Pressing Alt-SysRq on an i386, followed by one of the keys

Alt-Sysrq-s and the system promptly responded:
Sysrq: Emergency Sync
Emergency Sync complete
so it was my misunderstanding not a problem with Sysrq. Thanks for
pointing out my error.
