Hi Ben, thanks for the tip! tso was already disabled. I tried anyway and unfortunately it crashes as before. I filled a bug report (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197535) and marius@ is giving me a big help on it.

The one, fairly ugly workaround I've found that makes it work well enough is disable tso ( i.e. ifconfig re0 down && ifconfig re0 -tso && ifconfig re0 up ). This also seems to stop the panics under current. > > I'm not sure it will work for you - but it has on everyone of those interfaces I've dealt with. > > Good luck, > -bp > >> On Feb 13, 2015, at 8:06 AM, Luca Pizzamiglio <luca.pizzamiglio@gmail.com> wrote: >> >> Hi, I'm Luca, >> >> I've some issues using a PCIe Realtek Ethernet board: >> re0@pci0:3:0:0: class=0x020000 card=0x012310ec chip=0x816810ec rev=0x0c hdr=0x00 >> vendor = 'Realtek Semiconductor Co., Ltd.' >> device = 'RTL8111/8168B PCI Express Gigabit Ethernet controller' >> class = network >> subclass = ethernet >> bar [10] = type I/O Port, range 32, base 0x1000, size 256, enabled >> bar [18] = type Memory, range 64, base 0x90500000, size 4096, enabled >> bar [20] = type Prefetchable Memory, range 64, base 0x90400000, >> size 16384, enabled >> cap 01[40] = powerspec 3 supports D0 D1 D2 D3 current D0 >> cap 05[50] = MSI supports 1 message, 64 bit >> cap 10[70] = PCI-Express 2 endpoint IRQ 1 max data 128(128) link x1(x1) >> speed 2.5(2.5) ASPM disabled(L0s/L1) >> cap 11[b0] = MSI-X supports 4 messages >> Table in map 0x20[0x0], PBA in map 0x20[0x800] >> cap 03[d0] = VPD >> ecap 0001[100] = AER 1 0 fatal 0 non-fatal 0 corrected >> ecap 0002[140] = VC 1 max VC0 >> ecap 0003[160] = Serial 1 01000000684ce000 >> ecap 0018[170] = LTR 1 >> >> Rx and Tx don't work.
