Hi,
I have the following problem, and I suppose it has something to do with
my hardware, although I don't know the exact cause.
I have a Celeron 433 running in a MSI-6117 Motherboard (that's a Intel
LX based board with a 66 MHz frontside-bus). Since the onboard-IDE
controller can only handle hard-drives up to 8GB, I have a Promise
PDC20262 UDMA66 controller plugged into a PCI-slot. There's currently a
Maxtor 120GB hard-disk attached to it.
In random intervals (sometimes a few minutes, sometimes a few hours) I
get an error that looks like this:
ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=175339620
ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=175351972
ad4: WARNING - WRITE_DMA interrupt was seen but timeout fired LBA=175339629
ad4: WARNING - WRITE_DMA interrupt was seen but taskque stalled
LBA=175339620
- I tried several standard IDE cables and two different UDMA-66 cables.
(It feels like the error occurred more often with the UDMA-66 cables,
but it still occurs with standard IDE ones).
- I tried putting the card in a different PCI-slot
(No difference)
- I tried several different hard-drives (The error also occurs with a
UDMA-66 Maxtor 80 GB Hard-disk, but does not seem to occur with a 10GB
Fujitsu hard-disk (UDMA-33 only). So I thought that the Maxtor-drives
overheat, so I mounted one of them in an aluminium-frame and put in a
small cooler. The interval before an error appears increased quite a
lot. The overheating assumptions was also supported by my observations
that the drive fails less often with a UDMA-33-cable (half of the
frequency, half of the heat). Now the hard-drive is really cool, but the
error isn't entirely gone.
- I tried to update the IDE-card firmware, but it already has the most
recent version installed
This error (and especially the randomness) drives me nuts! I have really
no idea what I can do now.
Can anybody explain to me, what _exactly_ the error-message means?
Or does anybody have an idea which options I have for further
investigations?
Thanks
Paul
PS:
dmesg gives me (with the Maxtor connected via a standard IDE cable):
