Hi Shawn thank you very mach for your reply I've tried to enable pfmod again (now when my both interfaces are configured) and system boots without any problem!
Conclusions Installation procedure for solaris 10 asks for network interfaces configuration and I always do it Installation procedure for solaris SXDE don't asks for network interfaces configuration. I guess now solaris tried to configure interfaces automatically and fails to do it properly. So this is the reason why pfmod hangs at boot. Roman This message posted from opensolaris.org
