Hi,
I'm running a Promise Technology PDC20318 (SATA150 TX4) (rev 02)
controller in on of my servers and I gettig the following error from time
to time - espacially when there's high load on the disks:
ata6.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2
ata6.00: port_status 0x20200000
ata6.00: cmd 35/00:f8:95:6f:83/00:03:02:00:00/e0 tag 0 dma 520192 out

ata6.00: error: { ICRC ABRT }
ata6: soft resetting link
ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata6.00: configured for UDMA/100
ata6: EH complete
sd 5:0:0:0: [sdd] 488397168 512-byte hardware sectors (250059 MB)
sd 5:0:0:0: [sdd] Write Protect is off
sd 5:0:0:0: [sdd] Mode Sense: 00 3a 00 00
sd 5:0:0:0: [sdd] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
During this, the system hangs for about 10 seconds.
First I thought that this was related to the ASIC bug in the TX4 and
upgraded to 2.6.24-rc6 - but still the error occurs.
Some more information:
/dev/sda: Seagate ST3250620AS
/dev/sdb: Hitachi HDS722525VLSA80
/dev/sdc: Seagate ST3250620AS
/dev/sdd: Hitachi HDS722525VLSA80
Alltogether in a RAID10 (md).
The both Hitachi disks use to live in my workstation before I put them
into the server. They are about three years old.
When these both Hitachis where in the workstation, I had no problems
before about kernel 2.6.16 (I'm not sure). It might be related to change
from the old sata driver to the libata driver!?
In fact, in the workstation, *both* Hitachis produced errors with the
newer kernels, especially when I ran disk-indexing tools like beagle.
After moving them to the server together with the brand new Seagate
disks, only sdd makes problems. All the other disks never produced an
error like that.
NCQ Queue Depth is "1" for all disks.
Can someone tell me what to do?
Is the IBM disk "sdd" broken?
Could it be a cable problem?
Or is it the diver, though?
Regards
Volker
P.S.: please put me on cc:, I'm not on the list.
