Re: [PATCH V5] scsi: hpsa: disable device during shutdown

Sinan,

'Commit cc27b735ad3a ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts.

pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown.

This has been found to cause crashes on HP DL360 Gen9 machines during reboot due to hpsa driver not clearing the bus master bit during the shutdown procedure by calling pci_disable_device().

Disable device as part of the shutdown sequence.

Applied to 4.18/scsi-fixes. Thanks!
