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
