Strange message on ps -a

[Joerg Johannes <liste_joerg@gmx.de>]

Hello Everybody

The following message appears each time I make "ps" or "ps -a":

{floppy_open} {scsi_init_free}
Warning: /boot/System.map-2.2.17 does not match kernel data.

Then the running processes are listet just right. Any idea what happened
to my System.map? I compiled my own kernel (with buolt-in floppy and
scsi-support). Things ran fine for some time, this message came up
yesterday for the first time. I cannot remember having changed anything
in my base-configuration

Thanks

joerg
