Bug 857324

I think its a bug in the test to issue the warning in that routine.  It looks like we want to warn if we're acking data in an skb that we haven't yet copied to a user space buffer.  However, if we've copied all the data in the socket (i.e. if copied_seq == TCP_SKB_CB(skb)->end_seq, then we should be fine. Can you try with the patch I'm about to attach?

Created attachment 612819 [details]
patch to restrict warning case in tcp_rbuf_cleanup

have this too, with my intel wifi:
https://bugzilla.kernel.org/show_bug.cgi?id=47511

Yes, also without vmware (also note abrt detects the now closed bug #854367 as the duplicate)

No VMware here either, and I'm getting this on a bluetooth adapter (saw most people got the error related to wi-fi, which in my case works flawlessly)

Error seems to be related to bad bluetoothd teardown at the moment of going into sleep mode. Everything runs fine at boot time, then I close the lid or send the system to sleep, and the bug happens when I wake up the OS.  Bluetooth stack comes up, but the bluetooth mouse no longer works (thought it communicates OK and can be detected).

Here's the error I see at sleep time:

And when it resumes we get the attached trace.,  Can't guarantee is related, but seems quite likely based on the following string:

This is in the stable repo.  Not sure why bodhi didn't close the bug.
