Hi,

In sata_sil24.c, there's a special flag as shown below:
	SIL24_FLAG_PCIX_IRQ_WOC	= (1 << 24), /* IRQ loss errata on PCI-X */
Could someone explain the error condition and the rational behind the fix?

Thanks,
Fajun

It's a workaround for an erratum which is under NDA, so can't say much
about it.  :-(
