I have an i386 router with a fiber Intel GigE card ("Intel i82543GC 1000BASE-X Ethernet, rev. 2"). This is connected to a SX GBIC on aswitch, and I'm running numerous 802.1q VLANs across it. This is allworking fine.I have a card which has the same chip.I am trying to replace the 10/100 switches (with Gigabit GBIC ports) with full gigabit switches. I have a Dell 2724 with SX SFP's in it,and I tried connecting the i386 with wm(4) to one of them last night,after trunking that new switch into the existing fabric. I was getting 80% or more packet loss between my desktop and theStrange.
I also didn't expect it. :-)
What NetBSD version are you running? Could you give me the full dmesg and ifconfig wm0 of your system?
I am running a recent (late Jan, early Feb 2010) netbsd-5 image. dmesg and ifconfig output attached.
I'll try to reproduce the bug.PR#40981 is a bug that device timeouts occur, but I suspect that it's adifferent bug. http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=40981
It may be related, but the circumstances certainly seem different. And I'm seeing significant network communication issues, beyond only the messages, so that I think makes it a different issue.
Thanks... - Chris
