Hello
There seem to be an issue(s) in 2.6.18.1 and also other kernels with
high I/O and the sata_promise driver.
My Log gets filled with these messages with kernel 2.6.18.1 and 2.16.19-rc2-mm1 (from gentoo portage):
----snip
ata1: no sense translation for status: 0x50
ata1: translated ATA stat/err 0x50/00 to SCSI SK/ASC/ASCQ 0xb/00/00
ata1: status=0x50 { DriveReady SeekComplete }
----snip
The Results from kernel 2.6.18.1 are made with these following bonnie++ commands:
bonnie++ -d /mnt/raid-array/ -s 1024 -n 5 -u theo
bonnie++ -d /mnt/raid-array/ -s 4096 -n 5 -u theo
These messages i'm getting with kernel 2.6.17-gentoo-r8
----snip
ata2: status=0x50 { DriveReady SeekComplete }
sdb: Current: sense key=0x0
ASC=0x0 ASCQ=0x0
Info fld=0x10be
----snip
I have seen this error message on all versions of kernel 2.6 since the
beginning and also on kernel 2.4 and asked about this error message some
time ago, but didn't get an answer.
It happens on heavy random access (heavy headmovement) on disk but also
on fsck(.ext3). Since kernel 2.16 or 2.6.17 (since printing "Info
fld=xxxxxx) this error message is getting rare.
P.S. I've never seen any data corruption, so this is not a serious error
for me , but might be for others.
The Results from kernel 2.6.17-gentoo-r8 are made with several
concurrent copy workloads to Disk from Network with NFSv4 over a 100Mbit
NIC. Also made with bonnie++ with same results.
It seem to be the same failure over and over again.

Hope someone can use these Informations.
I would be glad to help with info on this, but on patch testing I#m a
bit careful because my computer is a productive system used on daily base
