Not sure if I can post here simply through replying to the email address,
but it's worth a shot.
Unfortunately, I had to leave town for a couple of days. I'll try to get the
full log once I'm back.

@Reinout -- not sure the exact cause of the crash/panic with the
2.6.38-8-generic #42 kernel, unfortunately the traces don't provide much
useful info, but probably the issue is solved with the usb fixes that
went after 2.6.38.2 (the testing kernel I posted is rebased to
2.6.38.4). Anyway, you still
Since the machine dies upon insertion of the USB disk i cannot issue a dmesg
command. I had to fiddle with netcat to get some form of output. It does not
even appear in the kernel log.
Anyway: here's a copy of the console output immediately after inserting the USB
disk with the standard kernel (
Herton, Let me try to provide you with some information to see if you are
right.
First here's the dmesg output of the testing kernel

Reinout, may be your issue is different, can you provide dmesg with the
oops? And full dmesg with the testing kernel.

Title:
Kernel panic upon in
I noticed similar behaviour on my system. With the standard ' linux-image-2.
2.6.38-8.42' i get consistent kernel panics with either the mouse or the USB3
disk inserted on the USB3 host port. So i installed the kernel provided here
and set the debugging options as requested.
Unfortunately with t
Thanks for the output, unfortunately the log is truncated because of the
much more extra debugging info. Can you add also log_buf_len=1M to the
kernel boot parameters and redo the test, attaching the resulting dmesg?

Here's the new dmesg output, running the new kernel with slub_debug.
Hope it helps.

Finally, here's the dmesg output after the same procedure, except I
booted with slub_debug.
Jeremy, sorry for mistagging. However, this bug is a regression, since
inserting a device in a usb 3.0 port worked just fine in maverick
meerkat.
On a sidenote: It was a long time ago I was involved in any
natty has no proposed candidates ergo, this cannot be a regression-

Herton,
I'll get around to do this as soon as I can. It might take a little
while though, our router here recently broke down so I can't ssh in from
another computer.

Khashayar, can you boot the kernel with slub_debug kernel boot
parameter? If you don't know how to add slub_debug, follow the guide at
https://wiki.ubuntu.com/Kernel/KernelBootParameters , feel free to ask
here if you have any doubt. After you boot with slub_debug, do the same
test and attach again
