[Bug 1547838] Re: ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops
a1291762, the next step is to fully commit bisect from kernel 2.6.22 to
3.19 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
After the offending commit (not kernel version) has been identified,
then please mark this report Status Confirmed.
Thank you for your understanding.

Title:
ADMtek ADM8511 "Pegasus II" USB Ethernet causes oops
Status in linux package in Ubuntu:
Incomplete
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.
