Red Hat Bugzilla – Bug 17326
SysRq Boot does not work
Last modified: 2008-05-01 11:37:58 EDT
SysRq + B ( Boot , should reboot the machine )
does not work for me. The other SysRq key all work.
Second, SysRq + L ( killalL , kill all processes )
freezes the computer. VT switching doesn't work anymore,
the Caps Lock LED doesn't change on the key press.
Weirdly the power-off button works.
It is a soft-power-off button and if the correct
code is not running, one must hold it for 4 seconds
to power off.
Same thing with Florence beta2 on an updated machine.
( it is still the same keyboard )
From the Documentation/sysrq.txt file:
'i' - Send a SIGKILL to all processes, except for init.
'l' - Send a SIGKILL to all processes, INCLUDING init. (Your system
will be non-functional after this.)
so the "L stops functioning" is not a bug but intended behavior.
The "b" is still a bug
Still doesn't work.
I patched to kernel to perform a reboot on SysRq+H instead
of SysRq+B and it works, pressing SysRq+H will reboot the system.
Seems like the keyboard can't handle certain key combinations.
For the record :
Keyboard is PS/2 with slovenian layout , Cherry G83.
