The only reason I ask is that I've rebooted the Linux SAN a few times to get past an error that occurs once or twice a week. I'm provisioning disk to ESXi 5.0 servers and have some test VMs on it. When the error occurs the logs look like the following: Feb 3 16:54:44 san kernel: [356059.826049] Uknown TMR function: 0x0d.

I'm not sure if there is something I can do to avoid this error or not. I was hoping the fixes in the master branch may have been the solution :) Here's another more recent one as well for good measure: Feb 6 16:00:39 san kernel: [189694.118344] Uknown TMR function: 0x0d.
