Hi all, Recently, I was testing one of 2.6.27-rc on arm device with sata_mv (integrated to soc) and there seems to be a problem. Controller seems to be working (perfectly) only with devices that does support SATA3.0 and NCQ31, rest of drives does not work at all or almost does not work. Note: sata_mv history in my tree is identical to the one is in linus's tree (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;f=drivers/ata/sata_mv.c;h=2b24ae58b52ee557e9d028e06e83de405a121a40;hb=7591103c08abade60aeddb432ed0686ddd0de1c6) at the moment. ============================================ This is output on boot with drive that system manages to see: -------------------------------------------------------------------------------
