"port is slow to respond" error freezes OS for seconds while reading HDs

[Dainaccio]

Sometimes, while reading data from HD, my OS hangs for about 15 seconds (gray window and no feedback).
The problem started with Gutsy but in Hardy it'is very frequent and makes Ubuntu almost unusable.

The PC is a notebook Acer Aspire 5630

Here the log:

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Dainaccio (superdinoz)]

I installed the last release Intrepid Ibex and the problem is here again (well.. It has never gone away since Gutsy).

the hardware is the same, the kernel is 2.6.27-11.

I have this error with my Acer Aspire 9410 running the latest Ubuntu 9.10:
ata1: port is slow to respond, please be patient (Status 0xd0)
ata1: device not ready (errno=-16), forcing hardreset
ata1: soft resetting link

Before I tried Fedora 12 with the same problem.
I found many links about this problem and applied the manual fix: insert a CD ( see the post http://ubuntuforums.org/showpost.php?p=2508650&postcount=5). It works but looks like a fix from my Grand Ma :).
Previously the laptop was running Windows XP for 3 1/2 years without problem (except when using the software to burn a CD/DVD, I got exactly the same issue, the UI freezing for few seconds but quite frequently).

[discord (colin.williams)]

I thought this problem had gone away, but recently I had an error, I'm not sure the compter may have been waking up from sleep / hibernation. I didn't have this problem with 9.10 but did with 9.04. It's happening again with 10.04. I think this bug may be a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/297058 . Anyway here are the errors I'm having:

[Dainaccio (superdinoz)]

Sorry for double post.

The error, that seemed to be gone, is here again. With the updates of the last months (I can't remember when precisely) and in the last release too. My hardware is the same of the first report.

It's really sad because it freezes the pc sometimes for tens of second a makes me angry. (OT expecially because I'm writing a thesis lol)
Bye.

[daniele80 (daniele80)]

I confirm this bug
on Ubuntu 10.04 Lucid Lynx.

The os randomly freezes for about 15 seconds.
I get rid of the freezes *only* when a cd-rom is mounted.
If I don't have a cd in the drive, the freezes come back.

I confirm this problem persists on Lucid Lynx Netbook Remix. Using Samsung N130 the system randomly freezes for about 15-25 seconds (sometimes the interface; sometimes even the mouse doesn't move). I get the following dmesg:

Same problem for me on 10.04.1 using my Samsung N140.

[Christopher M. Peñalver (penalvch)]

Dainaccio, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

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

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
