> As for adding this to 5.0-release; it's too late

Actually, I meant as something like -Release-p1

In any case, the DELAY(1) patch seemed to ALMOST completely solve the
problem for me. It manifested once after about 100 megs had been pushed
through the interface.

The patch you forgot to MFC makes my problem infinitely worse. After
applying it and rebuilding ther kernel (after cleaning the old object
files) the system is now almost totally inaccessible. Rather than being
getting errors now, the stack seems to totally halt on that session. I can
open new sessions, but the old sessions are totally locked. After about 20
minutes, I've had one become useable again. Seems strange to me, but you
know more about the driver than I do.

The problem is now manifesting almost as soon as I log in. I can get the
MOTD to show up usually, but most of the time I can't get the output from
'ls' to show up before it dies. Putty sometimes responds with an "invalid
CRC on packet" error. (2-10 minutes later it seems)

I'm moving back to the DELAY(1) patch until someone comes up with
something else to try.
