Default Bug#496917: BUG: soft lockup - CPU#1 stuck for 4096s! and crash (kvm guest)

Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-3
Severity: important


Using kvm 72, the guest is started with:
kvm -smp 2
-net nic,macaddr=DE:AD:BE:EF:21:71,model=virtio
-net tap,ifname=tap02,script=/etc/kvm/kvm-ifup
-net nic,macaddr=DE:AD:BE:EF:21:72,model=virtio
-net tap,ifname=tap12,script=/etc/kvm/kvm-ifup-web
-drive if=virtio,boot=on,file=/dev/vg0/web-root
-drive if=virtio,file=/dev/vg0/web-log
-drive if=virtio,file=/dev/vg0/web-srv
-drive if=virtio,file=/dev/vg0/web-swap
-m 3192
-kernel /boot/vmlinuz-2.6.26-1-amd64
-initrd /boot/initrd.img-2.6.26-1-amd64
-append "root=/dev/vda ro"
-curses

On the guest, I run the latest JDK from Sun 1.6.0_07, and the latest JBoss from
Redhat 4.2.3.GA, default configuration (except that it's started via runit:
exec chpst -u jboss:jboss -e ./env -o 65536 /opt/jboss/bin/run.sh -b <host>

After restarting it a few times, I get the following crash of the guest kernel:
