RE: acpi nic card flapping

["Yong Lee" <yonglee@telus.net>]

Hi all,

I’m hoping that someone out there can lend me a hand with a problem that we
were seeing.  I’m not very familiar with the acpi tool so please bear with
me.

We had an outage where we could not ssh into our web server and we had to do
a reboot from our console to get things running again.  It looks like an
acpi problem and I’m trying to figure out what was going on.  Was ACPI going
crazy or was it trying to report a problem condition that we were not aware
of.

What we saw in the dmesg log was this :

shpchp: Address64 -------- Resource unparsed

During the time of the outage we saw from our router logs that the
connection to the server was going up and down.

There was a lot of other messages on the console but our sysadmin guy didn’t
capture this.

We’re running redhat linux 2.6.9-34.0.2.ELsmp on intel xeon processors.  
We have 2 intel nic cards : Intel Corporation 82541GI/PI Gigabit Ethernet
Controller (rev 05)

Any light you can shed on this problem would be great.  Note that while the
kacpid kernel thread is running the acpid daemon was shut off during this
incident.

Many thanks,
Yong.
