SubjectRE: [patch] PCI: disable the MSI of AMD RS690

quirk_disable_msi() can not fix the issue in my debug,
quirk_msi_intx_disable_bug() which can fix SB700 SATA MSI bug does not
work either.
quirk_disable_all_msi is the only workaround I found.

If there is any other guy who also has one SB600+RS690 board, and can
help
to verify this RS690 MSI disablement patch with a new kernel version
such as
2.6.24-rc7, that's great.


BTW:
RS690 MSI disablement should NOT affect SB700 MSI, because as I know,
there will not be the combination of RS690+SB700 on the market.


Thanks
Shane
