I have a PCI network card that intermittently stops transmitting traffic under Fedora 15, perhaps once every couple days. The network traffic is not necessarily high when this randomly occurs, and usually the machine is relatively idle. Kernel: 2.6.38.8-32.fc15.x86_64 Driver: skge Network card: D-Link DGE-530T gigabit PCI card, firmware rev 11 Motherboard: Gigabyte GA-880GM-UD2H Rev 1.3 I do have multiple network cards, but all the others use the r8169 driver, and are seemingly unaffected. To get the network working again, I either have to reboot, or if I can unload (rmmod) and reload (modprobe) the skge driver then it will resume operating again. The kernel trace dump message is included below. I have tried to research this and found a couple other reports over the past 6 months or so of almost identical problems with this skge driver/D-Link card combination - but unfortunately I could find no responses. Does anybody have any idea what may be wrong (a driver bug, or just bad hardware)? Or if there is anything more I can do to provide information to anybody willing to look into this issue. Thanks.
