| *  What is the magic SysRQ key?
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| It is a 'magical' key combo you can hit which kernel will respond to
| regardless of whatever else it is doing, unless it is completely locked up.
| 
| *  How do I enable the magic SysRQ key?
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| You need to say "yes" to 'Magic SysRq key (CONFIG_MAGIC_SYSRQ)' when
| configuring the kernel. This option is only available in 2.1.x or later
| kernels.
| 
| *  How do I use the magic SysRQ key?
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| On x86   - You press the key combo 'ALT-SysRQ-<command key>'. Note - Some
|            (older?) may not have a key labeled 'SysRQ'. The 'SysRQ' key is
|            also known as the 'Print Screen' key.

| 's'     - Will attempt to sync all mounted filesystems.
