Hi all,
I have a problem with the RS480M2-IL mainboard from MSI.
The problem is that I cannot write with more than 29 MB/s to a disk on any
add-on PCI IDE/RAID controller, even not to a raid 0 array.
I even get only 14 MB/s to a raid 1 array.
I tried to attach a 3ware Escalade 7006-2 with 2 disks.
I even tried some unknown IDE controller (ITE chip) on the PCI slots.
I both tried OpenBSD/i386 and OpenBSD/amd64.
The onboard IDE controller is forced to use DMA mode, since it was 10x slower
otherwise because the controller did not report that DMA could be used.
I tried the disks and controllers on another mainboard,
and I could get at least 53 MB/s on the raid 0 array and 34 MB/s
to an individual disk.
Speeds were mesured with 'dd if=/dev/zero of=/mnt/100mb bs=1m count=100'
This is the dmesg from the OpenBSD/amd64 installed were i had to include
the twe driver myself. The same problem exists though with
OpenBSD/i386's GENERIC kernel.
Every suggestion is welcome, I already tried to tweak anything in the bios,
doesn't change a thing, FreeBSD also has this same problem.
