iSCSI connection errors with SLES10 SP3 update

2010-12-20 Thread Hannes Reinecke
Hi all, I just noticed that I've botched up header digests with the latest update for SLES10 SP3. So if you got trouble connecting and get loads of 'iscsi: detected conn error (1011)' please switch off header digests. I'm working on fixing this and will let you know once the issue is fixed.
