Date: Fri, 10 Aug 2007 23:39:25 +0200 Message-ID: <20070810213925.GB10855@elmicha> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Received: from mail.gmx.net ([213.165.64.20]:46122 "HELO mail.gmx.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with SMTP id S1752842AbXHJVj2 (ORCPT ); Fri, 10 Aug 2007 17:39:28 -0400 Content-Disposition: inline Sender: linux-serial-owner@vger.kernel.org List-Id: linux-serial@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: linux-serial@vger.kernel.org Hi, until 2.6.21, I had the normal assignments for ttyS0 and ttyS1: 00:08: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A 00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A With 2.6.22 I get the names <-> ports/irqs the other way around: 00:08: ttyS0 at I/O 0x2f8 (irq = 3) is a 16550A 00:09: ttyS1 at I/O 0x3f8 (irq = 4) is a 16550A Is this supposed to be that way? Should we reassign these names with udev? udev-114 doesn't seem to have built-in rules to assign the traditional names. Or could it be related to some brokeness in my BIOS (ACPI/PNP)? I'm using the 8250_pnp module (and it's the same with builtin serial modules). I made sure that I did not accidentally change the BIOS settings for the serial ports. I'm using Gentoo, but on the lirc list was a Fedora user with the same symptoms. Regards... Michael
