sata_mv

[Steven Gill]

Hi List,

I am having some issues getting my Marvell 6145 working on my Asus P5E 
ws pro motherboard working.  I am using a 3rd party patch to get the 
pata port working, but have not had success with my e-sata ports (on the 
board the 6145 drives 2 sata and 2 e-sata ports.  There are another 6 
sata ports driven by the onboard intel ich9).  When checking dmesg 
output, I see this:

ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16
PCI: Setting latency timer of device 0000:02:00.0 to 64
Marvell (S)ATA Controller is found, using IRQ 16.
Interrupt Error: 0x40000000 orgIntStatus: 0x40000001 completeSlot=0x1.

I am willing to help debug any issues, test patches, etc, but most 
importantly wanted to report the issue.  I know this is labelled as 
"highly experimental", but again, wanted to offer assistance in testing.

Regards,

Steve

Wrong driver.  sata_mv does *NOT* drive the 6145 chip.
Rather, that particular chip emulates AHCI, and uses the ahci driver.

Sorry for the mistake there.  I realized I was using a non-mainline 
driver to get PATA to work, but decided to move to a SATA DVD burner.  
When inserting a disk into the drive (when hooked to the Marvell 6145), 
I get the following:

I am currently running 2.26.2

I was able to sucessfully burn a CD when connecting this drive to the 
ICH9 controller sata port, but could not burn a dual layer dvd (There 
was a similar reset message)

Yeah, it looks to me as if libata still has DVD burner issues.
I used my SATA DVDRW drive to burn a Suse DVD the other day,
and the same drive refused to read the burnt disc without first rebooting.

linux-2.6.25.6

Disc was fine, though.  Single-layer.

Do you get error messages as well?  Of what kind?

There have been so many broken things in so many parts of the kernel of late,
that I'm just way too far behind in diagnosing/fixing them.   Or reporting them,
since many developers have stated they would rather not see a bug report
without a bisect.

But here's all that was in the logs for this particular bug.
These messages appeared when trying to read the freshly burned DVD,
both before and after eject/reinsert.  A reboot cured it:

To hazard a guess at the problem here, I'd say that perhaps the media change
went undetected, and so sr_media_change() never got called.

I'm no longer even sure what would trigger that call.

Hi I've put a server together, and it has a

Marvell Technology Group Ltd. MV88SX6041 4-port SATA II PCI-X Controller 

After a great deal of work I've got it booting with the .25 version of the marvel driver. 
But It's generating many many of these kinds of errors.

 Assertion failed! 0 == (sg_len & ~MV_DMA_BOUNDARY),drivers/scsi/sata_mv.c,mv_fill_sg,line=798


How close is the driver to being reliable enough to use in a single drive
environment? 

is there anything I can do to help debug further?
