From: Mark Halpaap To: linux-kernel@vger.kernel.org Content-Type: text/plain Content-Transfer-Encoding: 7bit X-Mailer: Ximian Evolution 1.0.5 Date: 02 Jun 2002 15:58:33 +0200 Message-Id: <1023026319.1602.81.camel@sam> Mime-Version: 1.0 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, beginning with 2.4.19-pre-x my system totally freezes whenever my DSL provider decides that a disconnect would be a good thing ("LCP terminated by peer"). The pppd then gets the message and shuts down the current connection, most likely to open a new connection soon after (dial on demand). Around this time the system freezes, either during the final staging of disconnect or during the early stages of reconnect, can't tell from the /var/log/messages fragments (see below). Both the scroll lock and caps lock button start blinking, i.e. kernel panic, I suppose. No trace of error messages anywhere (not on console, not in /var/log/messages). Any ideas anyone?
