F15 intermittent kernel dump with skge network driver for D-Link DGE-530T card

[Deron Meranda]

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.
