WARNING: interrupt level 6 not serviced

From: Two Dog Flats (j3ff9ack@yahoo.com)

Hello all,

I have seen this error in the messages file on multiple machines after
deploying the Recommended Patch Cluster dated March 29, 2005. I did
not see any of these during our testing before rolling out these
patches to 20+ production servers. All of these servers are either
Netra T1 or SunFire V120 servers, Solaris 8, 512 MB memory, 2-36 GB
SCSI drives and either qfe or GigaSwift ce quad Ethernet cards. I have
also included the output from "prtconf -v" below.

I searched the archives and Googled for the error with the result that:

A. Interrupt 6 typically refers to a network driver issue (but not
always), and

B. If anyone else has seen this lately, they haven't figured it out or
posted a summary.

I will be more than happy to summarize if someone can point me in the
right direction to find out more about this warning, or if I can ignore
the occasional unserviced interrupt.

Right now, the warnings are making me tired as I have our paging system
text message me all log entries that have "WARNING" in them...and these
entries are only happening at 3 and 4 AM :-).

Here are more details about one specific machine that has had 4 of
these messages:

Here are the messages from /var/adm/messages:
