[Bug 1591293] Re: kernel fails to boot from SSD on non AHCI chipset (NCQ unsupported)
I did test the kernel Joseph said:
linux-image-4.7.0-040700rc1-lowlatency_4.7.0-040700rc1.201606100619_amd64.deb
Bug is still there.
I did reset the PC as soon as kernel take too long to boot and began to inform that NCQ command was failing, with similar errors than with xenial kernel, such as:
equipment kernel: [ 64.970612] ata4.00: failed command: READ FPDMA QUEUED
equipment kernel: [ 64.970638] ata4.00: status: { DRDY }
equipment kernel: [ 64.994812] ata4: hard resetting link
After reset and reboot with libata.force=noncq nothing was logged to syslog. I didn't want to complete a fifteen minutes boot with a failing upstream kernel oriented to yakkety in my xenial installation, fearing it could break some bytes. I already spent too much time to install and configure xenial.
I hope this helps anyway.
BTW can't you just check if something has been done with upstream kernels to correct this behaviour?
Thanks for your job.

Title:
kernel fails to boot from SSD on non AHCI chipset (NCQ unsupported)
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu 16.04 64bits WON'T BOOT from a SSD Kinsgton Savage (2016) on chipset ASUS M2N68-AM SE (2010) with non-AHCI SATA2
SATA Settings: 32 bit transfers: ENABLED, AHCI mode: not available.
Fresh installed system FREEZES inmediatly after starting to boot, PC looses its video signal.
kern.log does not register anything.
This motherboard does not support AHCI, but the SSD does. Fresh
installed 16.04 kernel does not disable NCQ (AHCI).
Same system will slowly boot with errors when disabling 32 Bit transfers from BIOS, and freeze.
Same PC boot ubuntustudio 12.04 live usb automatically disabling NCQ when SSD is connected.
SAME SSD WILL BOOT without erros on chipset Intel Pinetrail-M with SATA3 and AHCI.
(Same SSD and both PC boot fresh Windows 10 in sixteen seconds without any issue.)
Expected behaviour:
Kernel recognizes that AHCI is not supported by the hardware, and then disables NCQ because it requires AHCI,
OR kernel recognizes that NCQ commands are failing and then disables NCQ,
and by disabling NCQ the system can boot without any problem.
Real behaviour:
Kernel only disables NCQ when SSD drives are on a blacklist, but does not disable it when the chipset does not support AHCI (NCQ). Kernel isn't disabling NCQ even when NCQ commands are failing. This way system won't boot, or will boot but then freeze.
It's not easy to understand why the system isn't booting. Many users
are replacing their hard drives with SSD to improve the performance of
their not-so-old PC, and if chipset does not support AHCI they will
need to do expert diagnosis and tweaks to make ubuntu boot.
Other tests:
SATA Settings: 32 BIT TRANSFER: DISABLED, AHCI: not available.
System boots from SSD with ATA errors and taking some minutes when it should take some seconds.
Kernel DOES NOT disable NCQ after failing (it does on 12.04 live, same PC)
System becomes definetly unresponsive a few minutes after start up, mouse pointer still moves but does not respond to clicks, and PC has to be hard reset.
(In the posterior boot, system cleans some orphan inodes for one of the dm-crypt volumes)

ANOTHER TESTS:
Ubuntu 16.04 64bits boot from SSD in a 2012 Intel Pinetrail-M with SATA3 ports, AHCI, and common BIOS. (non UEFI)
SATA Settings: AHCI mode: extended, AHCI extension: enabled, 32 bit transfers: enabled OR disabled.
System boots normally from SSD without any errors.

Then kernel finish booting and system works perfectly on Pine Trail M.
I will try to disable NCQ by parameter in the kernel run command, as M2N68AM-SE is my everyday-work PC.
