Hi, Is there a RELENG_8 version of this patch ? I have a server that used to shows this issue quite a bit, but has not since 7.3.2. I would be happy to stress it on the box. The patch above does not apply cleanly due to the netmap diffs, but I can manually merge if thats the only difference. em1: <Intel(R) PRO/1000 Network Connection 7.3.2> port 0x2000-0x201f mem 0xb4100000-0xb411ffff,0xb4120000-0xb4123fff irq 16 at device 0.0 on pci11 em1: Using MSIX interrupts with 3 vectors em1: [ITHREAD] em1: [ITHREAD] em1: [ITHREAD] em1: Ethernet address: 00:15:17:ed:68:a4 em1@pci0:11:0:0: class=0x020000 card=0x34ec8086 chip=0x10d38086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = 'Intel 82574L Gigabit Ethernet Controller (82574L)' class = network subclass = ethernet bar [10] = type Memory, range 32, base 0xb4100000, size 131072, enabled bar [18] = type I/O Port, range 32, base 0x2000, size 32, enabled bar [1c] = type Memory, range 32, base 0xb4120000, size 16384, enabled cap 01[c8] = powerspec 2 supports D0 D3 current D0 cap 05[d0] = MSI supports 1 message, 64 bit cap 10[e0] = PCI-Express 1 endpoint max data 128(256) link x1(x1) cap 11[a0] = MSI-X supports 5 messages in map 0x1c enabled ecap 0001[100] = AER 1 0 fatal 0 non-fatal 0 corrected ecap 0003[140] = Serial 1 001517ffffed68a4 -- ------------------- 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/
