hello Marek,
after applying the patch to dahdi-linux-2.2.1.1
when i run make i got this error.
usr/src/dahdi-linux-2.2.1.1/drivers/dahdi/wcb4xxp/base.c:60:2: error: #error
Sorry, wcb4xxp does not support chunksize != 8
make[3]: *** [/usr/src/dahdi-linux-2.2.1.1/drivers/dahdi/wcb4xxp/base.o]
Error 1
make[2]: *** [/usr/src/dahdi-linux-2.2.1.1/drivers/dahdi/wcb4xxp] Error 2
make[1]: *** [_module_/usr/src/dahdi-linux-2.2.1.1/drivers/dahdi] Error 2
make[1]: Leaving directory
`/usr/src/kernels/2.6.30.10-105.2.23.fc11.i686.PAE'
make: *** [modules] Error 2
Thanks
