Hello List, I am running rather heavy IO's on our MegaRAID controller on a Red Hat 3.0 Gold (2.4.21-4.Elsmp) 32 kernel. After a while, I notice that the OS sends the abort requests for commands that the driver has completed a while ago! I am using the unused struct scsi_cmnd->SCp fields to record the entry/exit timestamps and also the status of each commands while it is being processed. When I get the abort request, I am seeing that driver had completed the command already. I know that this is not an appropriate list to ask RH specific question. But I wasn't sure if it RH specific bug or if there are any known situations where 2.4 based kernels would try to _abort_ previously completed commands. I tried tracing the SCSI mid-layer code and I quickly got lost. Thanks in advance for any help.
