Hdlcdrv on kernel 2.2.3-15 RedHat6.0 filed?

[Vladimir Shuplyakov]

I have RedHat Linux 6.0 with 2.2.3-15 kernel
libax25-0.0.7
ax25tools-0.0.5
ax25utils-0.0.4

All was compiled fine , without any errors, but then I start hdlcdrv I had
an error message,
Also not start soundmodem module - also with error message.
What wrong? On old distributives all was fine.
