Hi Nick, Below is the requested dynamic_debug output. I highlighted the lines you wanted to convert to printk by "[TCM]" prefix. Few notes: I'm not sure if it is a 3.1 regression because I've made a number of changes to my SAN setup since 2.6.39 tests. Now, I have two targets (san1 and san2) that provide multipathed access to the same LUN under two different IQNs and two different NPs. I put a mark in the output to show where the successful san1 TPG cleanup ends and failed san2 TPG removal starts. Also, I simulate loss of cabling by setting a firewall rule "DROP all INPUT on port 3260" immediately before the TPG removal sequence. Don't know if it can have something to do with the bug but I mention it for completeness. Now, I want to repeat the test with only one TPG and also get kdb backtrace of rx/tx threads. Side question -- is there a way to play with kdb remotely? I don't have physical access to the servers today.
