(PM) "W1 DMA: Recieve Buffer Full"

I get lots of "W1 DMA: Recieve Buffer Full" messages on my OR-HS (one
every couple of seconds). I've looked at the archives and people have
said that usually means your network is congested.

I know that isn't the case because the OR-HS and the device all of the
traffic is going to are on a 3Com switch. It is a fairly busy switch,
and the OR-HS does see about a 1% collision rate.

This T1 is pretty much saturated (runs at around 80% average usually) -
can a OR-HS not really keep up with that much traffic?

I also have gotten the following message:

net: Bad wanted 69, got 1500, ident: 5 off: 56559 proto: 64 src: 66b46cf dst: e0714d0

What does that mean?

The other end of the link is a Cisco 7513, and it sends LCP_ECHO
requests every ten seconds. Sometimes though, I get bursts of

PPP recv(W1): Invalid header

instead (sometimes one such message, sometimes as many as a dozen).

The T1 has been tested repeatedly by the telco (who I trust - they are a
CLEC and know what they are doing), so it looks to me like the OR-HS
can't keep up with a full T1.

I don't speak for anybody but myself - that's enough trouble.
