Linux 2.6.24 sata_promise SATA300TX4 problems

Linux 2.6.24 sata_promise SATA300TX4 problems

[Peter Favrholdt]

Hi Mikael & list,

I have previously reported problems with my setup:

SATA300TX4 + 4 Seagate Barracuda ES 500GB

I just tested with 2.6.24. After copying approx 25GB of each drive using
  dd if=/dev/sd[abcd] of=/dev/null bs=1M
sda failed with the following message:

[ 1060.069489] ata1: SError: { 10B8B Dispar BadCRC TrStaTrns }
[ 1060.069498] ata1.00: cmd 25/00:00:90:2c:e6/00:02:01:00:00/e0 tag 0 
dma 262144 in
[ 1060.069501]          res 40/00:28:00:00:00/00:00:00:00:00/40 Emask 
0x4 (timeout)

I have included lspci and dmesg output below.

My system is rock solid using 2.6.21-rc2 with Mikael Pettersons 1.5Gbps 
patch.

I will happily test any patch/suggestions thrown towards me :-)

Best regards,

Peter

Mysterious. What you have there is a transmission error between the
controller and the disk, which is bad in and by itself, but then there's
a sequence of COMRESETs that fail to bring the port or disk back to life.

The original error is not a driver error but something caused by your
system, be it a dodgy cable, a poorly seated cable, or electrical
interference. But the failed COMRESETs is a concern as I've seen them
in other reports as well.

Me worried ...

So going back to 2.6.21-rc2 makes the system stable again? Can you do some
more testing to see at what point the system becomes less stable? I.e.,
2.6.21-rcI, 2.6.22, 2.6.22-rcJ, 2.6.23, or 2.6.24-rcJ?

FWIW, I just completed some testing of a 300 TX4 card with kernel 2.6.24,
including dd:s, fscks, mkfs:s, and copying about 400GB of data from one drive
(Samsung) to another (Seagate 7200.10) on that card, and I cannot seem to break it.

Hi Mikael,

Thanks for your reply :-)

Maybe I should try switching cables (again). Or it could be a 
motherboard issue (NFORCE2)?

I believe the important part is your 1.5Gbps patch which I applied to 
2.6.21-rc2. Maybe the reason for being stable is that the transmission 
error will not show up at that speed - thus not having anything to do 
with the kernel version. I'm quite sure the problem is there using 
2.6.21-rc2 at 3Gbps.

I believe it only happens if I stress all four drives simultanously. So 
maybe the transmission error is somehow related to the overall stress of 
the PCI bus/card/chip/whatever?

If it is not too much of a hassle, could you please make a 1.5Gbps patch 
for 2.6.24 for me to try out? If it solves the problem (without me ever 
touching the cables) we know for sure it is speed-related and not due to 
kernel version.

Still strange that the com resets does not help though (but maybe this 
is the drive which locks up?) :-/

Best regards,

Peter

No problem. I had intended to drop that patch after 2.6.24-rc8 as it
ought to be obsolete, but then again it might not be. It's available here:

Hi Mikael,

Thanks!

It works perfectly at 1.5Gbps :-)

I think that because it fails at 3Gbps it might eventually fail at 
1.5Gbps also... And the error handling was not robust (in my setup with 
these drives at 3Gbps).

If I can help investigate further, I'm happy to do that. I have a spare 
controller card so I could try swapping them.  Do you have any 
suggestions for what I should try next?

Best regards,

Peter

Hi Mikael & list,

I have previously reported problems with my setup:

SATA300TX4 + 4 Seagate Barracuda ES 500GB

Just for the record: using the same setup with linux kernel 2.6.25.4 
shows the same problem running at 3.0gbps:

Using Mikaels 1.5gbps patch produces no errors doing the same test.
