Hello! I have HP ProLiant BL460c G6 servers with Broadcom Corporation NetXtreme II BCM57711E 10-Gigabit PCIe controller. After enabling Virtual Server in kernel and placing server to the test environment with just 10Mbit/s traffic I see a lot of error messages in logs. I try different kernel versions 2.6.27.39, 2.6.31.2, 2.6.31.6 but every time I see the same error: With 2.6.31.x kernel: Nov 19 23:35:30 bsrvm8-1 kernel: ------------[ cut here ]------------ Nov 19 23:35:30 bsrvm8-1 kernel: WARNING: at net/core/dev.c:1563 skb_gso_segment+0x10f/0x260() Nov 19 23:35:30 bsrvm8-1 kernel: Hardware name: ProLiant BL460c G6 Nov 19 23:35:30 bsrvm8-1 kernel: bnx2x: caps=(0x198829, 0x0) len=719 data_len=119 ip_summed=1Pid: 0, comm: swapper Tainted: G W 2.6.31.2-lvs #1 Nov 19 23:35:30 bsrvm8-1 kernel: Call Trace: Nov 19 23:35:30 bsrvm8-1 kernel: <IRQ> [<ffffffff812c1b09>] ?
