And would you show me backtrace of panic? Yes, as I wrote, plugging and unplugging. Usually, there is no traffic I'm aware of, simply the - a hunch - attempt to renegotiate the connection triggers the crash. As I can force by bringing up and down the port on the switch. Of course you can get a panic/backtrace, but I need the weekend. I complained in another thread about the inability of getting a core - I use ELI encrypted swap, so I shot myself at that point. > > > I guess the Green IT issue is more a unlucky guess of mine and went > > hand in hand with the problem I face with CURRENT right now on some > > older, Non UEFI machines. > > > > Ok. > > [...] > > > > As requested the informations about re0 and rgephy0 on the laptop > > (Lenovo E540) > > > > [...] > > > > rgephy0: <RTL8251 1000BASE-T media interface> PHY 1 on miibus0 > > rgephy0: none, 10baseT, 10baseT-FDX, 10baseT-FDX-flow, 100baseTX, > > 100baseTX-FDX, 100baseTX-FDX-flow, 1000baseT-FDX, 1000baseT-FDX-master, > > 1000baseT-FDX-flow, 1000baseT-FDX-flow-master, auto, auto-flow > > > > re0: <RealTek 8168/8111 B/C/CP/D/DP/E/F/G PCIe Gigabit Ethernet> port > > 0x3000-0x30ff mem 0xf0d04000-0xf0d04fff,0xf0d00000-0xf0d03fff at device > > 0.0 on pci2 re0: Using 1 MSI-X message re0: ASPM disabled > > re0: Chip rev. 0x50800000 > > re0: MAC rev. 0x00100000 > > This looks like 8168GU controller. > > [...] > > > I use options netmap in kernel config, but the problem is also present > > without this option - just for the record. > > > > Yup, netmap(4) has nothing to do with the crash. > > Thanks. > _______________________________________________ > email@example.com mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
