Socket destroy delayed with 2.1.128

I just booted 2.1.128 on my fairly standard Pentium, and I noticed a
'Socket destroy delayed' message in the logs. Nothing seems to be
broken, but since I understand we're getting pretty close to 2.2 I
figured it would be good to work out any bugs.

This is 2.1.128 running on a Pentium 100. I forgot to comment out SMP
in the Makefile, so this is an SMP kernel running on a UP system.
Here's dmesg output:

Socket destroy delayed (r=0 w=1072)

The network card is a NetGear FA310TX with the Digital 21140 onboard.

I saw the "socket destroy delayed" before I even got to the login
prompt. The system's running Debian 2.0 with some -frozen pieces.

Please Cc: me on any replies; I will attempt to follow any discussion
via the archives.

HTH,
