Bug Description
sata_via does not recognize sata ports going up or down.
Controller is a
00:0f.0 RAID bus controller: VIA Technologies, Inc. VIA VT6420 SATA RAID Controller (rev 80)
Steps to reproduce:
Boot up computer with no esata Enclosure connected.
Connect eSata enclosure -> nothing happens no kernel message (dmesg) at all
When reloading the module (rmmod sata_via && modprobe sata_via) the drive is detected:

I'm pretty sure that hotpluging should work with this controller and sata_via.
The Hardy Heron Alpha2 release will be coming out soon. It will have an updated version of the kernel. It would be great if you could test with this new release and verify if this issue still exists. I'll be sure to update this report when Alpha2 is available. Thanks!
