I just installed SL5.3 on a Supermicro PDSBE motherboard and its disk i/o is
painfully slow; about 3MB/s. The system has SATA drives but the kernel sees
them as /dev/hdx devices. There is also a ata_piix message at the beginning
of bootup that says "no available legacy port". I'm guessing the failure to
recognize the SATA drives as /dev/sdx and the slow disk i/o are related to
this cryptic message.
I tried switching the SATA mode in the BIOS to compability instead of
enhanced. It didn't make any difference. I wasn't expecting any. The
compatibility vs native stuff, I thought, was something that was done when
SATA support for spotty. The SATA controller is an Intel ICH8 which I figure
should be well supported.
Any ideas on how to proceed? Build a custom kernel? Which I am reluctant to
do since I rely on SL for updates.
Try SL5.4 ?
