Hi, Andrew Morton: In 2.6.12-mm1 patch, there are some lines as follow: 300379 +static int 300380 +megaraid_reset(Scsi_Cmnd *cmd) 300381 +{ 300382 + adapter = (adapter_t *)cmd->device->host->hostdata; 300383 + int rc; 300384 + 300385 + spin_lock_irq(&adapter->lock); 300386 + rc = __megaraid_reset(cmd); 300387 + spin_unlock_irq(&adapter->lock); 300388 + 300389 + return rc; 300390 +} I think between line 300381 and 300382 should add follow line: adapter_t *adapter; The attachment is the patch, please confirm it. Best Regards Bob
