It means your are having network problems and your Service Guard cluster is reflecting the panics and trying to stay connected.....
If your cluster has not failed over...than it held. You may need to check your network connections for any hardware problems, since that looks to be where the SG panics are being triggered.

The btlan4 device is bouncing up and down. Like Rita says, MC/SG can cause this if you are not configured correctly. Check the network connections. Could also be a sign of a bad card that is intermittently going in and out.

Your 100 Mb lan card (driver=btlan) and the destination device (switch?) its plugged into are trying to autonegotiate between 10/100Mb and half/full duplex but cant do it, so they keep resetting, trying half, then full, then half etc. To fix this hard set your 100Mb land card to either half or full, and the same on the switch/hub its connected to.

Stefan has a good point there. Also check the configuration files in /etc/rc.config.d (hpbase100conf and hpbasetconf)

it does look to me that, the switch and the lan cards are set in different duplex modes and they are trying to negotiate for the speed and hence the this UP and DOWN are happening. The best way to start this is
First confirm what duplex the LAN card and the switch port can support. If both of them can support Full duplex then set both LAN CARD and switch port to Full Duplex. Other wise set Both of them to Half duplex.
Hope this helps.

I am not quite sure why the first couple of responses seem to think MC/SG is causing this symptom, but what you appear to have is aproblem between your 100BT card and the hub/switch it is connected to.
It is normally preferable to set the switch port to a fixed speed/duplex, and then to do the same with the card in the HP server.
one other point to check besides the card/switch is the physical cable.
I do know that if it is between I think 35 and 42 metres, this can cause similar problems.
Also ensure you havethe latest patches for this driver.
