PROBLEM: dma timeout errors on reads and large writes (sata_vsc on kernel 2.6.9)

PROBLEM: dma timeout errors on reads and large writes (sata_vsc on kernel 2.6.9)

[Atul Bhouraskar]

Hi,

I am building a linux-2.6.9 system with 4 250G SATA drives (using the
intel GD31244 controller).
I have compiled a monolithic kernel with Vitesse vsc SATA support, ACPI
and APM have been turned off (see config at end of message).
The kernel boots up properly and detects all drives correctly (see dmesg
below).
I can partition and initialize the drives without any problem (using
cfdisk and mke2fs).
I can read and write small files (<100MB) without any problem too.

But when I try to use any of the drives with large files (more than a
couple of GB), the process invariably hangs with the kernel spewing out
ATA timeout and other errors (see log below). It usually needs a write
of more than 5-6GB before it happens, but it usually occurs at around
50-100MB while reading. It is not possible to kill the hung process,
though the rest of the system continues to be responsive. Any further
access (even an 'ls') on *any* of the SATA drives usually instantly
meets with the same fate.

It can be reproduced in the following way:


[root@sdrs mnt]# cd /tmp
[root@sdrs tmp]# mkdir sata1
[root@sdrs tmp]# mount /dev/sdb1 sata1
[root@sdrs tmp]# dd if=/dev/zero of=sata1/test count=100000
100000+0 records in
100000+0 records out
 [root@sdrs tmp]# dd if=/dev/zero of=sata1/test count=1000000
1000000+0 records in
1000000+0 records out
[root@sdrs tmp]# dd if=/dev/zero of=sata1/test count=10000000
10000000+0 records in
10000000+0 records out
[root@sdrs tmp]# dd if=sata1/test of=/dev/null count=1000
1000+0 records in
1000+0 records out
[root@sdrs tmp]# dd if=sata1/test of=/dev/null count=10000
10000+0 records in
10000+0 records out
[root@sdrs tmp]# dd if=sata1/test of=/dev/null count=100000

What could be happening? I am sure the drives are ok as they are new and
work well in other systems. Have I forgotten to add something in my
kernel?

Any help would be appreciated.

I got a similar report via my employer as well.  I don't think anybody 
has really tested sata_vsc on the Intel controller, just the one that 
Vitesse put out.

You don't happen to have a spare controller, do you?

Hi Jeff,

Thanks for your quick reply. Unfortunately we have only one of the
controllers here now, though we might be getting a few more in January.

Is there some way I could assist you by doing some tests here and
reporting debug messages/logs etc?

I am sure there are many other people out there who would be looking for
a good driver for the intel 31244, so it would be a useful update for
them too.
