Greetings,
This is my first post, after having been searching around. A major
source of information was this[1] thread but it's old and the OP
changed hardware.
This is mine:
* Asus M2nPV-VM motherboard
* BIOS version 5005 (this was the last version ever released)
* Phenom II X4 910e CPU
* 8GiB DDR2 RAM (dual-channel 800MHz)
* 4 SATA drives:
** 2 Toshiba DTACA100 (ports SATA1 and 3)
** 2 WD Reds WD10EFRX (ports SATA2 and 4)
* ATI/AMD Radeon HD 5450 on a PCIe slot
The toshibas comprise a RAID1, on top of which is LVM with Debian
stable Wheezy 7.5, linux 3.2.0-4-amd64. My boot parameters are:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="iommu=noaperture acpi_enforce_resources=lax"
(no AGP and i'm trying to get lm-sensors to work)
The Reds have nothing yet (i'm RTFMing on ZFS) and they are the
problem: randomly, one or the other get disabled at boot.

It happens mostly with ata4 but it's also happened with ata2. The
issue seems to be this:
[ 2.364556] ata4.00: 268435455 sectors, multi 1: LBA NCQ (depth 31/32)
It should be LBA48 NCQ
These are the BIOS settings that seem relevant:
extended IDE drive: auto
access mode: auto
SATA controller 1,2: enabled
SATA DMA transfer: enabled
SATA port 3,4: enabled
SATA2 DMA transfer: enabled
Plug'n'play OS: yes
I have no clue whether this is because of the drives (hope not!), if
so, how can i go around it (forcing LBA48)? Or a misconfiguration
somewhere. The disks
are new and pass SMART tests.
Could this be ACPI/APIC related? Something about sata_nv?
Any pointers for further debugging/solutions would be welcome.
Cheers,
Nuno
