Subject: pppd service crash in linux-3.13.6
Date: Fri, 07 Mar 2014 21:19:59 +0000 [thread overview]
Message-ID: <531A37FF.4000509@totakura.in> (raw)
Hi,
Using linux-3.13.6, I observed the following output from the pppd kernel
thread. This happened when I tried to suspend my computer and it
*stops* the computer from suspending. Before going to suspend, I had
used ppp to connect via my bluetooth modem and I later found that the
connection was broken abruptly with a similar trace output.
Trace:
