Multiple ATA Exception Emask, NCQ disabled etc during boot

[Markus Kilås]

During boot I get several error messages like this below on my new laptop:

ata1.00: exception Emask 0x0 SAct 0x1 SErr 0x0 action 0x6 frozen
ata1.00: cmd 60/08:00:0f:0a:74/00:00:02:00:00/40 tag 0 ncq 4096 in
  res 50/00:b8:df:08:0d/00:00:00:00:00/40 Emask 0x2 (HSM violation)
ata1.00: status: { DRDY }

Sometimes there is just a few and after some time the boot continues and I can use the laptop but more often the messages repeats and the boot finally ends with the root partition mounted as read-only.

With dmesg I can also see that I got:
ata1.00: NCQ disabled due to excessive errors
ata1: hard resetting link

And a lot of this (but this might be an other issue):
ACPI: Transitioning device [FAN] to D3
ACPI: Unable to turn cooling device [ffff88013fa3aec0] 'off'

System:
Ubuntu 8.10
Linux markuz 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux
Laptop: Zepto Nox A15
Harddrive: Hitachi HTS72322

I changed the BIOS setting from AHCI to ATA and now I can boot Ubuntu and there is no Emask exceptions in the syslog. This works for me right now but shouldn't AHCI work?

I have had the same problem with my Nox A15. I described the problem to Zepto chat support and I got the advice to change BIOS setting to IDE. That seems to have solved my problem.

Hi Markus,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 353812

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hi, I am having this issue on an Acer Aspire 1810TZ with a fresh 10.04 install (kernel version 2.6.32-19-generic #28-Ubuntu). Boot is very slow and dmesg shows it is stuck after mounting the root partition with messages as described in the original report.

I resolved the problem by changing from AHCI to IDE in the laptop's BIOS.

Copied from #539467 bug.
I have the same problem:
Multiple ata1.00 errors even when pc is idle on Gigabyte GA-E7AUM-DS2H motherboard.
One disk already is dead (Seagate) - it was on Jaunty.
The next was going down (WD) on 10.04 fresh minimal install with nvidia proprietary drivers.
Switching off AHCI from bios worked for me as well.
