RE: AMD 760MPX dma_intr: error=0x40 { UncorrectableError }

[Manish Lachwani]

I have seen this errors on Seagate ST380021A 80 GB drive on a large scale in
our storage systems that make use of 3ware controllers. Seagate claims the
following reasons:

1. Weak Power supply
2. tempeature and heat
3. vibration

Although, the maxtor 160 GB drives do not show such problems at all. Such
problems can be eliminated though. From the SMART data, get the bad sectors
and remap them by writing to the raw device. Those pending sectors will get
remapped. However, the problems will persist with these drives. In our
boxes, the operating temperature is abt 55 C ...

I have recently observed a large frequency of this error on
a bunch of compute servers with brand new disks.

Nov 15 01:42:52 fnd0172 kernel: hdb: dma_intr: status=0x51 { DriveReady
SeekComplete Error }
Nov 15 01:42:52 fnd0172 kernel: hdb: dma_intr: error=0x40 {
UncorrectableError }, LBAsect=44763517, sector=11235856
Nov 15 01:42:52 fnd0172 kernel: end_request: I/O error, dev 03:42 (hdb),
sector 11235856

Configuration is the following:
Tyan 2466 motherboard which has AMD760MPX chipset, dual Athlon MP2000+
processors  (supports UltraATA100)

hda=Seagate ST340016A 40 GB drive, ext2 FS
hdb=Seagate ST380021A 80 GB drive, ext2 FS.

There are many entries in this mailing list saying that
the above error is a sign of a bad disk.  Seagate diagnostics
say so too.. It is just hard to believe that 30 hard drives could
go bad in less than a month.

I know errors of this type were common on machines with Serverworks
OSB4 chipsets.  Has anyone else heard of this error happening on
non-serverworks chipsets such as VIA or AMD?  And is the drive
really bad or will a low level format clear the bad blocks
and let the drive operate again?
