From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Message-ID: <403FBD07.9000500@nortelnetworks.com> From: Chris Friesen MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Subject: [uml-devel] BUG REPORT -- getting "registered fd 47 twice" Sender: user-mode-linux-devel-admin@lists.sourceforge.net Errors-To: user-mode-linux-devel-admin@lists.sourceforge.net List-Unsubscribe: , List-Id: The user-mode Linux development list List-Post: List-Help: List-Subscribe: , List-Archive: Date: Fri, 27 Feb 2004 16:56:23 -0500 To: User-mode-linux-devel@lists.sourceforge.net, User-mode-linux-user@lists.sourceforge.net Got a bug report for you guys, please CC me since I'm not subscribed... I've got a 2.4.24 kernel with the latest uml patch, running on a 2.4.19 host. UML is running just plain, no skas or /dev/anon. I'm using a whole bunch of boot args, enough that I had to expand the array in init/main.c. Anyways, when I boot it goes through the startup fine, but when it gives the login prompt I see this: DSC-0-0-0 login: Registering fd 47 twice Irqs : 3, 3 Ids : 0xa0261138, 0xa0261138 Registering fd 47 twice Irqs : 3, 3 Ids : 0xa0261138, 0xa0261138 The irq 3 corresponds to CONSOLE_IRQ. When I try and log in it spits out the following, once per character I type: find_irq_by_fd doesn't have descriptor 47 Then it starts spewing out the following message until I kill the process: Failed to forward -1439843404 to pid 17758, err = 9 Where 17758 is the pid for bash. With gdb I set a breakpoint in line_setup_irq, and ran a backtrace just before the first error message above. This is what I got: Breakpoint 5, line_setup_irq (fd=-1608117768, input=-1608117768, output=-1347667284, data=0xa0261200) at line.c:199 199 { (gdb) bt #0 line_setup_irq (fd=-1608117768, input=-1608117768, output=-1347667284, data=0xa0261200) at line.c:199 #1 0xa0126efe in enable_chan (chans=0xa0261200, data=0xa02611f8) at chan_kern.c:164 #2 0xa01284af in line_open (lines=0xa0261200, tty=0xaa75c000, opts=0x2f) at line.c:255 #3 0xa0126971 in open_console (tty=0x2f) at stdio_console.c:135 #4 0xa00efb07 in tty_open (inode=0xaa60d9e0, filp=0xaa380e20) at tty_io.c:1437 (gdb) bre So, somehow the generic tty_open stuff is giving strange behaviour. Any ideas what's going on?
