| [SCSI] mpt fusion: Enable MSI by default for SAS controllers
|
| This patch modifies the driver to enable MSI by default for all SAS chips.
|
causes a kexec of the RHEL 5.1 kernel to fail.
root cause: 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.
