Hi Seokmann, When failing in megaraid_queue_command(), is not scsi_cmnd(io request) lost? I think that I fix this issue. Please check the code. (See attached file: linux-2.6.12-rc1-megaraid-queuecommand-error-midlayer-retry-fix.patch) The patching order is: - linux-2.6.12-rc1-megaraid-isr-quiescent-race-fix.patch - linux-2.6.12-rc1-megaraid-outstanding_cmds-atomic.patch - linux-2.6.12-rc1-megaraid-queuecommand-error-midlayer-retry-fix.patch BTW, Are the max number of commands that FW is treatable at the same time 128? For the megaraid2 driver, it was 127. Which is correct? I continue the driver's debugging further. Thanks -- Haruo
