That happens to me, also. I've found that tapping shift, alt, and control
on both sides of the keyboard, and hitting an invalid sysrq sequence again
will fix the problem. (ie, something like alt-sysrq-z). Switching to another

The Magic SysRQ system works by registering key operations against a key op
lookup table, which is defined in 'drivers/char/sysrq.c'. This key table has
a number of operations registered into it at compile time, but is mutable,
and 4 functions are exported for interface to it: __sysrq_lock_table,
__sysrq_unlock_table, __sysrq_get_key_op, and __sysrq_put_key_op. The
functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined
in the header itself, and the REGISTER and UNREGISTER macros are built from
these. More complex (and dangerous!) manipulations of the table are possible
using these functions, but you must be careful to always lock the table before
you read or write from it, and to unlock it again when you are done. (And of
course, to never ever leave an invalid pointer in the table). Null pointers in
the table are always safe :)
and 2 functions are exported for interface to it:
register_sysrq_key and unregister_sysrq_key.
Of course, never ever leave an invalid pointer in the table. I.e., when
your module that called register_sysrq_key() exits, it must call
unregister_sysrq_key() to clean up the sysrq key table entry that it used.
Null pointers in the table are always safe. :)
If for some reason you feel the need to call the handle_sysrq function from
within a function called by handle_sysrq, you must be aware that you are in
