Subject: sata_nv times out for BD-ROM iHOS104-08
Hello,
I recently got the iHOS-104-08 Blu-ray reader from LiteOn after hearing
customer reviews and a company statement that it works in Linux, but it
just doesn't work on my hardware combination. I saw previous posts here
and elsewhere on sata_nv specific problems, so I hope you can help me, or
at least I can report this properly for future fixes.
I have an ASUS P5NSLI motherboard with a Core2Duo E6400 CPU and a Nvidia
MCP51 SATA controller (rev a1). On this, I have two other SATA disks (in
Nvidia RAID0 configuration) that I boot from both in Linux and Windows and
I have been using this computer for several years without problems. The
LiteOn BD-ROM is attached to the 3rd SATA port (RAID disabled in BIOS) and
I was able to read DVDs on Windows XP. In Linux, with the latest stable
kernel 2.6.32 (note I'm running a 32-bit linux on 64-bit machine for
historical reasons), this is what I get at boot time:
# dmesg | grep ata3
ata3: SATA max UDMA/133 cmd 0x9e0 ctl 0xbe0 bmdma 0xe800 irq 20
ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata3.00: ATAPI: ATAPI iHOS104, WL08, max UDMA/100

ata3.00: qc timeout (cmd 0xa0)

ata3: limiting SATA link speed to 1.5 Gbps
ata3.00: limiting speed to UDMA/100:PIO3
ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata3.00: configured for UDMA/100
ata3.00: qc timeout (cmd 0xa0)
ata3.00: TEST_UNIT_READY failed (err_mask=0x5)
ata3.00: disabled
ata3: hard resetting link
ata3: nv: skipping hardreset on occupied port
ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata3: EH complete
In the end the device does not appear in my SCSI device list (see output
of lsscsi below) and I cannot access it. Curiously, I get 0 interrupts
from this SATA controller (see /proc/interrupts at bottom of email).
I tried playing with both sata_nv options, such as ADMA, MSI and SWNCQ. I
learned from posts here that MCP51 doesn't have support for ADMA, but
either way the messages I get did not change. I also failed to force DMA
and speed selection behavior using libata.dma and libata.force on the
kernel command-line. I wasn't able to influence sata_nv's decisions any
bit. "acpi=off noapic" and "acpi_use_time_override" also did not help. I
have a working HPET timer in the BIOS.
I was unable to get another driver like the SATA AHCI or one of the PATA
drivers to take over this device. Is that even possible?
I would appreciate any suggestions and would happily debug this a little
further. And, of course, happy holidays everybody. Details of my
configuration follow.
