Dear Mr Garzik,

I am currently having trouble with the new libata kernel subsystem (My
system broke after 2.6.21 I believe). After much fruitless googling
and trawling through the libata code (I am *no* kernel programmer!) I
took the serious, final step of bugging you.

Ten or so minutes after boot (long enough for my two IDE Sony DW-G120A
DVD writers to spin down) I start getting these error messages in my
kernel logs:

[ 6317.817041] ata4.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

ad nauseam.

(I am running kernel 2.6.27-11, amd64. I have also tried 2.6.29, and
the messages are the same)

My DVD writers then cease to function.

My initial thoughts are that my spun-down devices are taking too long
to respond to requests from the kernel. I braced myself and then dived
in to the icy waters of the kernel sources to see if there was a
timeout I could increase. However, there are several structs with
timeouts in libata-eh.c, and the last thing my poor kernel needs is a
moron like myself twiddling random constants.

Could you please let me know if you think I am on the right track? Or
maybe suggest a timeout to twiddle?

Many thanks, and many apologies for interrupting you.

Kind Regards,

Matt Grice

What type of system hardware?  What libata driver?

If its ahci, try using ata_piix.  I am beginning to think that ATAPI on 
AHCI is broken.

Otherwise, "timeout" generally means your hardware stopped sending 
interrupts, which could indicate a non-libata problem.  Timeouts are 
often symptoms of broken PCI MSI interrupts, for examples.

I use a SATAPI DVD-writer on AHCI (Intel 965) on a semi-regular
basis, and it's never had any issues with recent 2.6.2x kernels.

Are you able to rip audio CDs?

Hi! Many thanks for all of your responses, I'll try and deal with all
of the issues in one email. ;)

Hardware is an ECS KV2-Lite motherboard with an AMD Athlon64 X2 Dual
Core Processor 4200+. DVD-ROM drives are Sony DW-G120A.

My version of libata (from libata.h and dmesg) is 3.00.

I am using the VIA driver:

matt@Dexter64:~$ lsmod | grep ata
pata_via               18180  2
sata_via               17668  0
ata_generic            14212  0
pata_acpi              13568  0
libata                201312  4 pata_via,sata_via,ata_generic,pata_acpi
scsi_mod              183160  4 sr_mod,sd_mod,sg,libata
dock                   18464  1 libata
matt@Dexter64:~$


Please find attached my dmesg.

Jeff - when the errors start, I am unable to play / rip audio CDs.

Many thanks in advance for your help,

Matt Grice

PS - How do you find out if a drive has been forced from DMA to PIO
mode during operation?

I tend to doubt that the driver is doing the wrong thing. I suspect it's 
more that ATAPI devices on SATA are about as standards-compliant in 
general as ATAPI devices on PATA (which is to say not very good) and 
some of them break if the controller does something slightly differently 
or with different timing, which is quite possible in AHCI mode.

Tejun was looking at some SATA analyzer traces of a few drives that were 
apparently failing consistently on AHCI. Tejun, did you get anywhere 
with this? Even if the trace doesn't reveal any invalid behavior, if it 
includes high-precision timing data it would be interesting to compare 
that to the results on a working controller..

Hello,

I've tested everything including recording and cd ripping and most of
my devices seem happy but you never know.

I need to take a deeper look at that but in general I couldn't find
anything standing out.  After a series of ATAPI changes (IIRC, the DMA
padding change was the last thing), most ATAPI bug reports got
resolved and I'm not getting many ATAPI failure bug reports other than
recent ahci ones anymore.  I'm not sure whethre it indicates that we
finally got it right or something else tho.

Jeff, what kind of failure are you seeing?

Thanks.

Hardware:  SATA DVD-ROM/CD-RW devices, AHCI, ICH$foo

Reading and writing data CDs and DVDs works fine.  Ripping audio CDs 
using gRip application leads to timeouts almost immediately.

Well, it's a potentially unusual transfer length compared to other 
commands, which might be part of it. Do you have some error output? It 
would be useful to look at the reported failed CDB.

ATA command timeouts are usually pretty long (like 30 seconds) so 
usually if they time out something is wrong, or the drive has really 
gone into the weeds.

It looks like your drives are running at PIO mode 0 after the fault 
happens. What are they running at before? Full dmesg output from bootup 
might be useful..
