[Kernel-packages] [Bug 1062667] Re: USB mounted SATA disk disconnects

2013-09-16 Thread Tom Brown
I ran lsusb as root. When I ran it within a few seconds of plugging in
the device it wasn't included, 10 seconds was enough.

Bug description:
  I'm having a problem with a SATA disk connected to a USB adapter. The
  disk is detected and its partitions mounted  but after I use it for a
  few seconds to minutes the adapter disappears and dmesg lists errors.
  If I don't use the disk it stays healthy but running 'sudo cat
  /dev/sdb5  /dev/null' consistently causes a failure within a minute.
  The disk works well connected to the internal slot of the same machine
  and the adapter works well with a 40GB IDE disk I have on hand.

apport information

** Description changed:

  I'm having a problem with a SATA disk connected to a USB adapter. The
  disk is detected and its partitions mounted  but after I use it for a
  few seconds to minutes the adapter disappears and dmesg lists errors. If
  I don't use the disk it stays healthy but running 'sudo cat /dev/sdb5 
  /dev/null' consistently causes a failure within a minute. The disk works
  well connected to the internal slot of the same machine and the adapter
  works well with a 40GB IDE disk I have on hand.

2013-09-14 Thread Tom Brown
In #9 I'm not sure what you mean by Please do not test the daily folder, but 
the one all the way at the bottom.
I did a clean install of saucy using 
http://cdimage.ubuntu.com/daily-live/current/ and reproduced the bug. I then 
installed a kernel from the newest directory mentioning saucy in 
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D and reproduced it again.

Title:
  USB mounted SATA disk disconnects

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I'm having a problem with a SATA disk connected to a USB adapter. The
  disk is detected and its partitions mounted  but after I use it for a
  few seconds to minutes the adapter disappears and dmesg lists errors.
  If I don't use the disk it stays healthy but running 'sudo cat
  /dev/sdb5  /dev/null' consistently causes a failure within a minute.
  The disk works well connected to the internal slot of the same machine
  and the adapter works well with a 40GB IDE disk I have on hand.

  I looked at a similar looking bug,

[Kernel-packages] [Bug 1062667] Re: USB mounted SATA disk disconnects

2013-09-14 Thread Christopher M. Penalver
Tom Brown, as per http://download.lenovo.com/express/ddfm.html an update
is available for your BIOS (1.40). If you update to this, does it change
anything?

If not, could you please both specify what happened, and provide the output of 
the following terminal command:
sudo dmidecode -s bios-version  sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Thank you for your understanding.

[Kernel-packages] [Bug 1062667] Re: USB mounted SATA disk disconnects

2013-08-11 Thread Christopher M. Penalver
Tom Brown, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
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-rc4

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

If you are unable to test the mainline kernel, please comment as to why 
specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

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.

** Tags added: needs-kernel-logs needs-upstream-testing regression-
potential

** Changed in: linux (Ubuntu)

Title:
  USB mounted SATA disk disconnects

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm having a problem with a SATA disk connected to a USB adapter. The
  disk is detected and its partitions mounted  but after I use it for a
  few seconds to minutes the adapter disappears and dmesg lists errors.
  If I don't use the disk it stays healthy but running 'sudo cat
  /dev/sdb5  /dev/null' consistently causes a failure within a minute.
  The disk works well connected to the internal slot of the same machine
  and the adapter works well with a 40GB IDE disk I have on hand.

  I looked at a similar looking bug, 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1012291
  and booted a kernel from
  http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.27-precise/
