I am looking for stability and find this possibly disconcerting.
It looks like you are right about cosmetic for the speed test is about the
same in either. In Generic atacontrol cannot determine the mode at all and
in stable it shows up but as the wrong thing, udma100 SATA instead of SATA300.
dmesg reports on both the same:
atapci0: <Intel ICH7 SATA300 controller> port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xf000-0xf00f at device 31.2 on pci0
ata0: <ATA channel 0> on atapci0
ata0: [ITHREAD]
ata1: <ATA channel 1> on atapci0
ata1: [ITHREAD]
I noticed the following line in stable compile from sysctl, I find out it
reports that in generic also.
hptmv.status: RocketRAID 18xx SATA Controller driver Version v1.16
So I added nodevice hptmv
rebuild and It took it out but there was no improvement in results.
Kernel additions at the end.
So, if it is of no matter then cool, if you want me to do something just
let me know.
thx,
John
