https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265714 --- Comment #66 from Tomasz "CeDeROM" CEDRO <tomek@cedro.info> --- That sysctl dump was from within the stall, interface was up but the connectivity failed, had to restart network by hand to get it running again (service netif stop; /etc/netstart). Stuff below is after igc0 restart, got back up, but then I switched to ix0 and put igc0 down, no reboot so maybe something interesting is still here. I am working on ix0 right now. igc is extremely unreliable here and always craps itself in the middle or work.. how this is frustrating on your own local desktop now imagine you loose network on a remote machine. # # PCICONF # igc0@pci0:132:0:0: class=0x020000 rev=0x04 hdr=0x00 vendor=0x8086 device=0x125c subvendor=0x8086 subdevice=0x0000 cap 01[40] = powerspec 3 supports D0 D3 current D0 cap 05[50] = MSI supports 1 message, 64 bit, vector masks cap 11[70] = MSI-X supports 5 messages, enabled Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] = PCI-Express 2 endpoint max data 256(512) FLR RO NS max read 512 link x1(x1) speed 5.0(5.0) ASPM L1(L1) ecap 0001[100] = AER 2 0 fatal 1 non-fatal 1 corrected ecap 0003[140] = Serial 1 [XXX] ecap 0018[1c0] = LTR 1 ecap 001f[1f0] = Precision Time Measurement 1 ecap 001e[1e0] = L1 PM Substates 1 # # VMSTAT # irq151: igc0:rxq0 1075529 61 irq152: igc0:rxq1 1905162 108 irq153: igc0:rxq2 683268 39 irq154: igc0:rxq3 630179 36 irq155: igc0:aq 6 0 # # NETSTAT # Name Mtu Network Address Ipkts Ierrs Idrop Ibytes Opkts Oerrs Obytes Coll Drop igc0 1500 <Link#1> [XXX] 8503350 322 0 11337485568 2336649 0 292561991 0 0 # # FIX CHECK # L1PM capability offset: 0x1e0 L1PM CTL1 offset: 0x1e8 L1PM CTL1 value: 0x408c001b I226 ASPM L1.2 enable: CLEAR (workaround active) -- You are receiving this mail because: You are the assignee for the bug.home | help
