I setup a 2.2.6 knfs dual-pII server with the raid patches, with raid0
running across 3 18G disks. Things were running fine for about a week
and then started experiencing kernel oopses quite regularly. I thought
it may have been knfsd, so I switched back to user space nfsd but with
no luck. I finally ran a ksymoops and it seems raid0_map is the culprit.
Can anyone help?
Regards,
Shaun
