I've made some tests with 2.6.1 and 2.6.1-mm2. Good news: RAID1 works on two SATA disks with the IDE VIA driver (via82cxxx). At least after a while (see below). Bug 1: Doing a "modprobe via82cxxx" fails, since it tries to aquire ide0 and ide1 even though they are used by other drivers. Statically linked, it takes ide2 and ide3, just as it should. My ide0 and ide1 are PATA connectors that I'd like to keep even though the SATA connectors are activated. The siimage driver behaves correctly here, but only with the -mm2 version. Bug 2: Using the RAID1 array while it is being synced causes data corruption. When the sync is complete, everything seems to work fine. /Basic
