Now, how should I go on? I could enable Sound again and raise the "Storm-Limit" via sysctl and close the PR. However, as I already exchanged Sound Card, NIC and Mainboard (and all these Components (except for the Mainboard) work fine in a i386 FreeBSD-machine) it seems there is either something wrong woth the Chipset-Support in FreeBSD/amd64 OR the Chipset itself may be buggy, the Board's Design could be crap or something like this. MTIA!
