To address the issue, check current link state after driving MII_TICK. This should fix a regression introduced in r185753 on fast ethernet controllers. --- I don't have any issue related to that anymore. The problem is that I get link UP/DOWN a few times per hour on 3 identical machines that I dumped/restored. They are all pluged in a Cisco switch that works fine for every other PCs. Jan 26 06:09:15 term005 kernel: re0: link state changed to DOWN Jan 26 06:09:17 term005 kernel: re0: link state changed to UP I tried to switch cables, but I got the same result. There is the pciconf -lv output: re0@pci0:3:0:0: class=0x020000 card=0x02831028 chip=0x816810ec rev=0x02 hdr=0x00 vendor = 'Realtek Semiconductor' device = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC' class = network subclass = ethernet There is the output of vmstat -i: interrupt total rate irq18: re0 ehci0++ 63766 0 irq19: atapci0 277001 3 cpu0: timer 156068748 1961 Total 156409515 1966 Could it be related to the fact that there is re0 and ehci0++ on the same IRQ? Thank you for your help, Martin
