Related to my other message I found that, with my current keyboard, Magic SysRq is not working. It is definitely compiled into the kernel.
Documentation/sysrq.txt in the kernel tree suggested that the SysRq sending a strange scan code may be the reason.
Running showkey -s gives me the following codes for SysRq:
0xe0 0x2a 0xe0 0x37 - on key down 0xe0 0xaa 0xe0 0xb7 - on key up.
This does not match the description in setkeycodes which says that keys generate one or two byte sequences whereas this is clearly a four byte sequence.
Has anyone seen anything similar or have any ideas if the necessary mapping can be established?
Regards, Steve.
