I'm not aware of a 5015MT+ model. Maybe you mean 5015M-MT+ or 5015M-T+? We have two 5015M-T+ boxes, one running RELENG_7 and one running RELENG_6, and neither exhibit this problem. Here's relevant em(4) information from both boxes; I do find the vmstat -i IRQ on the 2nd box a little odd, but operationally it seems fine. box1 (RELENG_6) =============== em0: <Intel(R) PRO/1000 Network Connection Version - 6.2.9> port 0x4000-0x401f mem 0xe0200000-0xe021ffff irq 16 at device 0.0 on pci13 em1: <Intel(R) PRO/1000 Network Connection Version - 6.2.9> port 0x5000-0x501f mem 0xe0300000-0xe031ffff irq 17 at device 0.0 on pci14 irq16: em0 uhci3 117371806 11 irq17: em1 49605005 4 box2 (RELENG_7) =============== em0: <Intel(R) PRO/1000 Network Connection Version - 6.5.3> port 0x4000-0x401f mem 0xe8000000-0xe801ffff irq 16 at device 0.0 on pci13 em1: <Intel(R) PRO/1000 Network Connection Version - 6.5.3> port 0x5000-0x501f mem 0xe8200000-0xe821ffff irq 17 at device 0.0 on pci14 irq256: em0 502854 4 irq257: em1 5438 0 On box2, IRQ 16 is also shared with uhci3 and vgapci0, but vmstat doesn't seem to show that. uhci3: <UHCI (generic) USB controller> port 0x3060-0x307f irq 16 at device 29.3 on pci0 vgapci0: <VGA-compatible display> port 0x6000-0x60ff mem 0xe0000000-0xe7ffffff,0xe8300000-0xe830ffff irq 16 at device 0.0 on pci15 -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
