Mmm.. I doubt that sil24 is the only SATA controller with
this issue. The sata_qstor device, for example, requires PHY reset
*followed* by SRST if one wants to reliably detect a port multiplier.
Maybe the chipset drivers should simply do PHY / SRST as they're told,
and have libata-core ensure PHY + SRST before doing PM detection?
Cheers
