Ir-keytable -u: each time I press Power I get a different remotewakeup code

I have this problem with different remotes (nec, rc5, rc6).
example:

Received IRMP code: remotewakeup='0x0000390a', decode_type='0x4', remotewakeupmask='0x000037ff'
Received IRMP code: remotewakeup='0x00003550', decode_type='0x4', remotewakeupmask='0x000037ff'

Received IRMP code: remotewakeup='0x00003d4a', decode_type='0x4', remotewakeupmask='0x000037ff'
Received IRMP code: remotewakeup='0x00003bf4', decode_type='0x4', remotewakeupmask='0x000037ff'
Received IRMP code: remotewakeup='0x00003814', decode_type='0x4', remotewakeupmask='0x000037ff'
Received IRMP code: remotewakeup='0x00003814', decode_type='0x4', remotewakeupmask='0x000037ff'

Sometimes (with other remotes) I even get different remotewakeupmask codes. I tried all of them, but with none of them the box wakes up. It is a meson-ir. (The remote which came with the box works, but has not enough keys.)

Some reading for you.
