Code snippet for the same-

crashdump_enable &&
instance->crash_dump_fw_support &&
instanc
as: MFI IO timeout handling
Killing adapter in case of this DCMD failure should be limited to Fusion
adapters only. Per controller's instance variable allow_fw_scan is removed
as pd_list_not_supported better reflect the purpose.

This patchset has few small fixes/optimizations. Please consider this
for next release.
Sumit Saxena (4):
megaraid_sas: reduce memory footprints in kdump mode
megaraid_sas: call ISR function to clean up pending replies in OCR
path
megaraid_sas: task management code optimizations
2. Do not allocate memory for system info buffer and PD info buffer.
3. Disable performance oriented features e.g. Disable RDPQ mode, disable dual
queue depth,
restrict to single MSI-x vector.

the same command will be in
outstanding/pendingcommands list of driver and refires same command from IO
timeout thread after chip reset
which will again FAULT firmware and evntually causes kill adapter.

for MFI adapters,

I did not see the last sent mail on linux-scsi, so resending!!. Please
contact through LSI support channel. There is fix in applications for
such issues. Newer release of apps(which is used to create VD) should
fix the issue seen by you. I am not sure about application release
process. LSI support
