A8N-SLI Premium + Si 3114R + RAID5 of Hitachi Deskstar T7K250 -- locks up during install

[Malachi de Ælfweald]

I have tried this with 6-BETA1 and 6-BETA3.

I noticed the A8N-SLI Deluxe was supported, so thought that the majority of 
the Premium would be as well.

I am using the Silicon Image RAID controller instead of the NVidia one, 
because it supports RAID5 and the nVidia does not.
The RAID5 was configured in the BIOS.

During boot (bootonly.iso) it goes through autodetection, seems to see 
everything OK except that it detects the Si 3114R as "SATA 150" and it 
should be "SATA 300" because it is SATAII not SATAI.

It then gets to the following and locks up:

ad12: 238475MB <HDT722525DLA380 V440A80A> at ata6-master SATA150
ad14: 238475MB <HDT722525DLA380 V440A80A> at ata7-master SATA150
ad16: 238475MB <HDT722525DLA380 V440A80A> at ata8-master SATA150
ad18: 238475MB <HDT722525DLA380 V440A80A> at ata9-master SATA150

So, it appears that it finds each drive, instead of the RAID.
It appears that it detects the controller as SATA 1 instead of SATA 2.
It locks up as soon as it detects the hard drives.


Any thoughts?

Thanks,
