Once upon a time, Rick Stevens <ricks(a)nerd.com> said:
Oh, BTW, Fedora 10 kernels appear to be compiled with SysRq enabled.
At least mine are (x86_64):
CONFIG_MAGIC_SYSRQ=y
AFAIK all RHL, Fedora, and RHEL kernels have had this for many years.
The default is to disable it during boot (when /etc/sysctl.conf is
loaded) for security; you can re-enable it at any time (for one-time use
or permanently) with sysctl.
