private APN (in GSM network)

Hi
I've got problem with setup private APN in one of polish provider.
If setup is for normal access to internet (APN "internet") everything goes
smoothly.
If I change the APN name to "stawoz.pl" i cannot login. In var/logs/debug
can be seen that
there is problem with IPCP... I use modem ES75 (MC75 siemens). In windows
both apns are working correctly (on the same modem, same sim card)

help please...

logs and conf files are :
