Hi,
In kdump, when second kernel is initializing after the crash of first kernel
then devices might not initialize properly in second kernel becuase devices
are not in reset state.
It was suggested that drivers can be hardened to handle this situation.
A driver can reset the underlying device while it is initializing and then
go ahead with rest of the initialization. This reset can be performed based
on additional commandline option passed to the kernel.
I was trying the same for MPT fusion driver but somehow reset does not
seem to be working. Diagnostic reset fails.
I am attaching the test patch and logs. Could you please suggest what is
amiss?
Following are the scsi controllers in my machine.
05:07.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 (rev 07)
05:07.1 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 (rev 07)
07:05.0 SCSI storage controller: Adaptec AIC-7892A U160/m (rev 02)
Following is the error message. Full logs are attached with mail.
