After a couple of days on heavy load card's driver begins with: msk0: watchdog timeout msk0: watchdog timeout msk0: link state changed to DOWN msk0: link state changed to UP msk0: watchdog timeout msk0: link state changed to DOWN msk0: link state changed to UP and no traffic can pass this interface If msk is used as module then only kldunload/kldload brings interface back online. It seems to me to be the same bug as kern/116853 but on another hardware pciconf -lv: mskc0@pci0:2:0:0: class=0x020000 card=0x4b001186 chip=0x4b001186 rev=0x13 hdr=0x00 vendor = 'D-Link System Inc' device = 'DGE-560T PCIe Gigabit Ethernet Adapter' class = network subclass = ethernet After applying yongari's patches from kern/116853 card become some more stable, but still begins with "watchdog timeout" after a week of heavy traffic. If PCI MSI/MSI-X is disabled then bug dissappears, but it seems strange to me, because PCI-Ex cards supports MSI in specification, so the problem seems to be in software >How-To-Repeat: use D-Link DGE-560T adapter and try to transfer big files (DVD ISO for example) through it. >Fix: place hw.pci.enable_msix=0 hw.pci.enable_msi=0 in /boot/loader.conf >Release-Note: >Audit-Trail: >Unformatted:
