The first involves enabling qla2xxx debugging at modprobe qla2xxx time with: modprobe qla2xxx ql2xextended_error_logging=0x1e40f000 and the second is enabling tcm_qla2xxx debugging (via debugfs + CONFIG_DYNAMIC_DEBUG=y) with: echo 'module tcm_qla2xxx +p' > /debug/dynamic_debugging/control Having the logs with both of these debug bits enabled would be very helpful in pinpointing the issue. Also, adding CC' for Roland + Joern, as they where the last ones to touched this specific piece of code.. Roland + Joern, I know that at some point you had converted from btree -> radix trees due to some issues in lib/btree.c code, but never pushed this conversion patch for tcm_qla2xxx upstream. Can you give an idea of what caused to conversion to radix trees, and if the bug reported here is similar..?
