issues with em, ndis & 1 gig RAM in -current

Wed Jun 30 09:27:27 PDT 2004

For the past week or so I've been having issues with the em module for
my network card. The link yo-yos every 5-10 seconds making the
connection barely usable at best, and fills up dmesg output with the
following:

em0: Link is up 100 Mbps Full Duplex
em0: Link is Down
em0: Link is up 100 Mbps Full Duplex
em0: Link is Down
[repeated ad nauseum]

I first noticed this with a system I'd built on the 22nd, and after
cvsupping again last night, the problem still persists. I've already
tried different network cables, ports on the switch, etc, and am
convinced enough at this point that the problem is not hardware related
to write to this list and beg for help. Ironically, this is the
interface which I used to install the system, but I've since used
another wireless card for networking, which leads me to my second
problem with -current.

I'm using ndis in order to use a Linksys WMP11v2.7 (Broadcom chipset)
wireless card with -current, and it works great, even supporting the
802.11 encryption, until I increase the machine's RAM from 1G to 2G.
After doing so, the card still initializes and appears as ndis0, however
its status continually reports that no carrier is detected, and
ifconfig calls to the device either hang or fail. Removing the extra gig
of RAM returns the card to a working state. I've alraedy shuffled the
RAM around in various configurations, and used memtest86 to test the
RAM. Everything tests out OK. I've heard that the current state of ndis
can be dodgy, so I bring up this issue merely to try and be helpful. I'd
be plenty happy with using the em module for networking and having the
full 2G of RAM installed.

The machine in question is a 3.0GHz Northwood Pentium 4 with
hyperthreading enabled, with an 865G motherboard. I'm using DDR 400 RAM
in dual-channel mode. I've attached dmesg output from booting with 1G
RAM, please let me know if there's anything else I can provide to help
debug this.

best,
