[PATCH] scsi: megaraid_sas: fix kdump kernel boot hung caused by JBOD

[xiakaixu1987]

when kernel crash, and kexec into kdump kernel, megaraid_sas will hung and
print follow error logs

I've recently run into this exact issue on a arm64 machine with Avago 
3408 controller. This patch fixed the issue. Thank you.

Hi Martin, Xiaoming Gao, Kai Liu,

It is a known firmware issue and has been fixed. Please update to the
latest firmware available in the Broadcom support website.
Please let me know if you need any further information.

Thanks,

Hi Chandrakanth,

Could you let me know which megaraid based controllers are affected by 
this issue? All or some models or some generations?

Best regards,
Kai Liu

Hi Kai Liu,

Gen3 (Invader) and Gen3.5 (Ventura/Aero) generations of controllers are
affected.

Hi Chandrakanth,

My card is not one of these but it's also problematic:

# lspci -nn|grep 3408
02:00.0 RAID bus controller [0104]: Broadcom / LSI MegaRAID Tri-Mode SAS3408 [1000:0017] (rev 01)

According to megaraid_sas.h it's Tomcat:

#define PCI_DEVICE_ID_LSI_TOMCAT                    0x0017

According to product information on broadcom.com the card model is 
9440-8i. So I tried to upgrade to the latest firmware version 
51.13.0-3223 but I got these error:

# ./storcli64 /c0 download file=9440-8i_nopad.rom

I tried few more versions from broadcom website, they all failed with 
the same "image corrupted" error.

Here is the controller information:

Hi Kai Liu,

Tomcat (Device ID: 0017) belongs to Gen3.5 controllers (Ventura family of
controllers). So this issue is applicable.
As this is an OEM specific firmware, Please contact Broadcom support team in
order get the correct firmware image.
