Subject: tty Linux 3.7: possible circular locking dependency detected

Hello all,

i've seen two possible circular locking dependencies with my bluetooth dialup
setup. The dmesg outputs are attached.

Any idea?

I'll check, if i can reproduce this dmesg output.
Please let me know, if you need additional infos.

Best regards,
Oliver
