| [SCSI] mpt fusion: Enable MSI by default for SAS controllers
|
| This patch modifies the driver to enable MSI by default for all SAS chips.
|
cause kexec RHEL 5.1 kernel fail.
root casue: the rhel 5.1 kernel still use INTx emulation.
and mptscsih_shutdown doesn't call pci_disable_msi to reenable INTx on kexec path
so try to call mptsas_remove in mptsas_shutdown.
then pci_disable_msi will be called via mptsas_remove==>mptscih_remove==>
mpt_detach.
