Message-ID: <20030426034923.GA1450@galacticasoftware.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.28i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi all, I am having some serious problems with the serial driver in 2.4.20 kenrnel (from Debian) compiled with GCC 2.95.4 My server is a dual PPro with ECC memory. It has never crashed until I started using the serial port for the modem. During a connection, it suddenly froze with no keyboard response at all and _nothing_ on the screen. I thought maybe something overheated or what not. Two days later, I tried using the modem once more. After about 30 minutes and 1.5M later, there was a hard crash once more. I never experienced that with a non-SMP machine. And I never used SMP with serial driver... serial is compiled as module. Any ideas? - Adam
