[Bug 882540] Re: kernel crash whenever it is accessed

[Werner Kuballa]

Hello Stefan

Looks like this package fixed the problem.  Before I installed this
package, iSCSI target would crash shortly after the initiator
connected.  After the installation of your package, iSCSI has not
crashed.

cheers,
Werner
