Everything will be fine with kernel before 7/25 and you'll loose ar0 with the code after 7/25. >Fix: According to Soren there's metadata-code redesign needed but he has no idea yet and no time to do that, so remove cmd649 and sil0680 support from at least "ataraid", but that's too late I think. Urgently there must be some notice about the possibillity of data loss when upgrading from 5.2.1 to 5.3, and of course of the loss of RAID functionality. >Release-Note: >Audit-Trail: >Unformatted:
