soft lockup with CIFS makes image unresponsive

[Bobby Powers]

running aki-3aa54d53 (ubuntu-lucid-amd64-linux-image-2.6.32-306-ec2-v-2.6.32-306.11-kernel), with a share from a neighboring ec2 (also running lucid) mounted. I'm able to negotiate a tcp connection, but can't actually log in via ssh (or see any of the content served with apache2/tomcat6). Any help would be appreciated (I've attached as much console output as ec2-get-console-output would give me).

not to be pushy, but any ideas? This is troubling to me, as this is a production server that clients will be using in a few days, and I see no clear causes/solutions (aside from not using samba, which I would like to avoid if possible)
