[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops


a1291762, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:

Please note, an error to install the kernel does not fit the criteria of

Also, you don't need to apport-collect further unless specifically
requested to do so.

Once testing of the latest upstream kernel is complete, please mark this
report Status Confirmed. Please let us know your results.

Thank you for your understanding.

  ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops

Status in linux package in Ubuntu:

Bug description:
  This is a rather old USB ethernet adapter. It worked fine for me with
  older distributions (including Ubuntu 10.04). I noticed it causing
  problems after upgrading to 14.04 and stopped using it as a result
  (since I needed reliable USB ethernet for work). I was also not
  completely sure if it was this device causing the issue or interplay
  between this device and a number of other networking USB devices that
  were used at work.

  I'd like to use this ethernet adapter at home but the machine is
  running Ubuntu 14.04 and the issue persists.

  I have collected some information that might help. I'm happy to try
  more things to collect information if that will help.

  I'm running Ubuntu 14.04 server 64-bit. I just rebooted so I'm running
  the latest updates.

  I was told to run ubuntu-bug linux but I'm not sure how much useful
  stuff is included in that. I'm including the kernel log which has some
  bad stuff happening in it. Not sure if it got the system-freezing oops
  or just the errors leading up to that.

  It feels like a bug in the driver that corrupts memory because I see
  issues with network-related things (eg. a ping crashed, but the next
  ping didn't), leading to a full-system freeze.

  This machine has been happily running Ubuntu for a looong time (though
  it was only recently upgraded to Ubuntu 14.04, previously it had been
  running 10.04). I have not had stability issues with the machine but
  plugging in the USB Ethernet reliably makes it freeze within minutes.
  The symptoms also match what I saw on my machine at work.
