Subject: Re: sata_sil24: external raid storage mistaken as port multiplier

Hi,

I got it fixed by removing ATA_FLAG_PMP from the SIL24_COMMON_FLAGS.

Could someone turn this into a module option?

The external raid case might in fact has a built-in port multiplier,
but the case can only be configured as raid0 and raid1.

I suspect that Linux tries to to access the drives separately, which fails.
