An 'ifconfig ix0 mtu 1500' works fine, but 'ifconfig ix0 mtu 1501' causes a panic. It was either a "RX ring hdr initialization failed!" or a "RX ring pkt initialization failed!" (sorry, I did not write it down because I thought it would be in the logs). This is with a 8-STABLE cvsup'd yesterday: FreeBSD XXXXXXX 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #4: Sun May 23 17:23:39 CEST 2010 root@XXXXX:/usr/obj/usr/src/sys/GENERIC amd64 ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.1.7> port 0xece0-0xecff mem 0xdf1a0000-0xdf1bffff,0xdf1c0000-0xdf1fffff, 0xdf19c000-0xdf19ffff irq 34 at device 0.0 on pci5 ix0: Using MSIX interrupts with 9 vectors ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: [ITHREAD] ix0: Ethernet address: 00:1b:21:49:56:61 ix0: PCI Express Bus: Speed 2.5Gb/s Width x8 ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=5bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,LRO> ether 00:1b:21:49:56:61 inet 10.0.1.1 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet autoselect (10Gbase-SR <full-duplex>) status: active rvdp
