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
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.
