Cisco ASA 5555-X drop problem

Hey

Have run in to a strange problem with the ASA-5555-X (one of many in a row). When traffic flows between the inside interfaces I get drops in traffic (testing with ordinary 32 ping). Both traffic leaving in ipsec tunnels and traffic passing straigh through. When placing myself in the outside vlan and testing with ping the drops doesn't happend. The logs dont say anything when it happens, using wireshark now to look for problems. Stats from the outside interface is as follows:

Interface GigabitEthernet0/0 "telenor", is up, line protocol is up

Do anyone have tip for me.

More information. The unit connected to the ASA5555-X and now also a ASA5505 (for test) is a Catalyst 3560.

The Catalyst is supplied by my ISP which is Telenor Norway. They cant see any problems on the router.

It looks like the packet loss happens between the ASA and router. We have tried setting the boxes to auto/auto and static to 100fdx.

Anyone have any suggestions ?
