SiI 0680 and 5.3

[Volker Eckert]

i learned from the 5.3 errata that raid functionality for the 
above mentioned chipset was broken: 

"...ata raid support .... is non-functional ... raid config
stored under 5.2 or prior may be corrupted"

since i had severe problems getting 5.2.1 to work reliably 
(the machine would just reboot under high network load)
i tested it with 5.3. initially it didn't recognise the raid1
but after recreating it (without losing any data disk) it 
just worked fine. moreover, the reboots are gone.

what am i missing? or is it that only the 5.2 _configuration_
has gotten corrupted but the new created 5.3 configuration
is ok??

any hints?
thanks!
