>Description:
	<RAID(1) support for sil0680 and 0649 is still broken in BETA2>
>How-To-Repeat:
	<Create a stripeset with 5.2.1-rel disc2 (like 'atacontrol create
RAID1 ad4 ad6' and make sure after a reboot with 5.2.1-live there is a
ar0) and boot with BETA2 (or -current since about 2 months) and there's
no ar0. Even the creation of ar0 fails. Also the controllers metadata
is ignored wich makes it impossible to rebuild arrays via the controllers
BIOS. Another problem IMO is that you can write to subdisks of an arry
(if there is ar0 you also can write to ad4 which is member of ar0, this
wasn't possible some time ago!)>
>Fix:

	Don't know, if it isn't possible to support these controllers
like users would expect it's far better to remove support in general
than to to deliver -stable with this pitfall.

State-Changed-By: sos 
State-Changed-When: Mon Sep 13 11:09:13 GMT 2004 
State-Changed-Why:  
You just need to recreate the RAID since for now the metadata format 
for those controllers have changed. 
This will most likely get addressed in the net major overhaul of 
ata-raid.c
