Externally it appears that way (the stamp on the chip reads 3132), however it identifies as a Silicon Image type 0x0242 according to lspci. sata_sil24 does not attach. I made the trivial addition to sata_sil24 device id table and it appears to work. Performance is about the same as I get with the same drives on the onboard sata_via (about 78MB/s sequential read, 72MB/s write) and md mirror resyncing reflects this. This is on a FC6 system (2.6.19-1.2911.fc6 SMP x86_64). I compared with 2.6.20 sources and sata_sil24 seems to have some cosmetic changes, but nothing that would help this it seems. When the patched module loads I see a 'failed to IDENTIFY' and spurious interrupt message. These do not seem to recur during use. Anything to worry about? I note that lspci reports a subvendor of Adaptec, type 0x242. Is it correct to just patch (like below) where one vendor appears to have 'cloaked' a generic board? --- 04:00.0 RAID bus controller: Silicon Image, Inc.
