Message-ID: <4DFB3DA1.7060603@wpkg.org> Date: Fri, 17 Jun 2011 13:42:25 +0200 From: Tomasz Chmielewski <mangoo@...g.org> To: linux-kernel@...r.kernel.org Subject: change kernel logging (console=ttyS0) without reboot? Generally, most production systems don't like to be restarted unnecessarily. I was wondering if it's possible to change kernel logging without a restart? Say, I connected a serial cable to the server, but kernel was not booted with anything like console=ttyS0,19200 in its command line. So anything produced by the kernel will not show up on ttyS0. Can I still somehow make the kernel to log to ttyS0, without restarting it (I can make syslog do it, but let's assume the syslog crashed and I'm mostly interested in catching a kernel oops/panic etc.)? -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
