Hi Marius, Thanks for looking. The ifconfig output was after I turned off tso as Harry suggested to try. Its been 24hrs and I have not seen any resets. I will wait another 36hrs or so and then turn it back on to see if the problem comes back. this link is 100Mb. The other em nic onboard is a different chip. Its at gigabit and seems to work fine with tso enabled # pciconf -lvcb em1 em1@pci0:14:0:0: class=0x020000 card=0x109a15d9 chip=0x109a8086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = '82573L Gigabit Ethernet Controller' class = network subclass = ethernet bar [10] = type Memory, range 32, base 0xe8b00000, size 131072, enabled bar [18] = type I/O Port, range 32, base 0x6000, size 32, enabled cap 01[c8] = powerspec 2 supports D0 D3 current D0 cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message cap 10[e0] = PCI-Express 1 endpoint max data 128(256) RO NS link x1(x1) speed 2.5(2.5) ecap 0001[100] = AER 1 0 fatal 1 non-fatal 0 corrected ecap 0003[140] = Serial 1 003048ffff9c59f1 # ifconfig em1 em1: flags=8843 metric 0 mtu 1500 options=4219b ether 00:30:48:9c:59:f1 inet6 fe80::230:48ff:fe9c:59f1%em1 prefixlen 64 scopeid 0x2 nd6 options=23 media: Ethernet autoselect (1000baseT ) status: active The original problem nic is em0 pciconf -lvcb em0 em0@pci0:13:0:0: class=0x020000 card=0x108c15d9 chip=0x108c8086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = '82573E Gigabit Ethernet Controller (Copper)' class = network subclass = ethernet bar [10] = type Memory, range 32, base 0xe8a00000, size 131072, enabled bar [18] = type I/O Port, range 32, base 0x5000, size 32, enabled cap 01[c8] = powerspec 2 supports D0 D3 current D0 cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message cap 10[e0] = PCI-Express 1 endpoint max data 128(256) RO NS link x1(x1) speed 2.5(2.5) ecap 0001[100] = AER 1 0 fatal 1 non-fatal 0 corrected ecap 0003[140] = Serial 1 003048ffff9c59f0 -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
