Kernel panic with Ubuntu ppa-mainline 3.14.1 kernel

[daikerjohn]

I'm seeing quite a few panics on the 3.14.x kernel series.
I'm using HEAD on kernel_version branch at the moment: 8727c18

Here are some of the panics:

I have added logging for a condition that looks suspicious. Please pull again and try the new code. Watch the dmesg output for a line that says "purb->actual_length (NN) > USB_INTR_CONTENT_LENGTH (56)\n".

[daikerjohn]

Sadly, haven't seen the message since I rebuilt and reloaded. I did notice a different panic though... and it appeared before your additional commit.

[11412.634502] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

[lwfinger]

We are looking into this one. By the way, these are not panics, merely warnings. A panic is reserved for those cases where the kernel cannot continue without the possibility of doing damage to file systems, etc. A warning only calls attention to some condition that is wrong, but so wrong that execution cannot continue.

[daikerjohn]

Thanks for taking a look!
If you prefer to pass along patches instead of committing, I can apply and build accordingly. I know my way around 'patch' and 'diff'.
My apologies for the misuse of panic/warning. Thanks for educating me along the way!

[lwfinger]

Jes Sorensen found this one. Fixes to both master and kernel-version have been pushed. Thanks for your patience.
