Subject: [rt2x00usb] sleeping function called from invalid context at kernel/locking/mutex.c:616
Date: Thu, 26 Dec 2013 13:00:50 +0100 [thread overview]
Message-ID: <11195731.87o6OySWVz@al> (raw)
Hi,
I just found this BUG in my kernel log[2]. This Ralink RT5372 USB
adapter (148f:5372) was in AP mode with wireshark (dumpcap) enabled.
Four seconds hereafter, a DHCP client connected so I guess it occurred
during association or authentication. This is almost 3.13-rc5,
v3.13-rc4-256-gb7000ad. .config is available in this repo[1].
Let me know if you need more information. Happy holidays!
Regards,
Peter
