Hi all,
I have an ECS 945p-a v1.1 motherboard which has an ICH7 chipset. I have
connected to this three SATA drives, a PATA HD, and a PATA DVD drive.
When I try to copy a large block of data (1GB file) from a PATA drive to
a SATA drive, it brings my system to a near stop. The CPU meter hits
50% (dual core) and any action I attempt will take about 10-20 seconds
to execute. If I cancel the process, the system returns to normal
(after about 1 minute). This also happens on transfers from the DVD.
A not so good explaination is that the ata_piix module is controlling
the SATA drives, and some other module (piix, ide_generic?) is
controlling the PATA drives, such that both are trying to use the same
device (the ICH7) and somehow this is blowing up the DMA part of the
file transfer?
My root is on the SATA drives. In my initramfs/modules I have ata_piix
although this doesn't seem to make a difference. My fs are XFS for root
and FAT32 on the PATA drives. (My root is actually software RAID0
across two of the SATA drives). My BIOS doesn't seem to have an AHCI
option.
Anyone have any ideas why file transfers are taking over my CPU? Details
below...
Thanks,
Peter
