Hi Bart, There is no IB workload in the domU's. In this particular case there are 2 dom0s connected together both acting as SRP targets and initators. Their are sometimes vms running on these dom0s but they aren't currently in production so they aren't doing very much at the moment. The workload is typically one of adding and removing luns to ini_groups, rescan the host to ensure they are removed cleanly etc. As far as I can tell this would have to manifest as a race condition as it can go for about 2 or so weeks without occuring. Also worth noting is that I have a similar setup running on 2.6.32 with no issues also a pvops dom0 using SCST and ib_srp. Could it be your patch series introduced the bug? Those are the only patches we have in our tree that effect SRP.
