Summary: Grub hangs on unattended boot if serial and console are configured Project: GNU GRUB Submitted by: None Submitted on: Mon 10/31/05 at 21:04 Category: Booting Severity: Major Priority: 5 - Normal Item Group: None Status: None Privacy: Public Assigned to: None Originator Name: Chris Gardiner Originator Email: [EMAIL PROTECTED] Open/Closed: Open Release: 0.93 Reproducibility: Every Time Planned Release: _______________________________________________________ Details: Hi everyone, I'm hoping someine can help me out here. I believe this is a bug but can't be 100% sure I didn't just miss something. I have a CentOS (Basically redhat) system installed fresh off the CD's using Grub 0.93. Everything boots fine under normal circumstances. I recently added support for the system to run with a serial console and I'm running into issues. I have configured everything such that the console and serial terminal all work fine with one exception. When I attempt to boot the system unattended, the system hangs waiting for a key press to dertermine which console is the one to output to. By documentation, Grub is supposed to output to the device which has a key press during the time out interval or after the timeout, default to the first in the list. However, what I am seeing happening is that it times out and then hangs. Worst of all, if I wait long enough, no keypress on either the serial or the console will recover the system and I need to hard reboot. This is a SERIOUS problem. It basically means that I can not remotely reboot any server using a serial concertrator for console access without wathing the system come up. I am including a copy of my grub.conf file just in case I made some sort of simple mistake someone might see. Thanks! #boot=/dev/sda default=0 timeout=10 serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1 terminal --dumb --timeout=2 serial console #terminal --timeout=5 serial console ##splashimage=(hd0,0)/grub/splash.xpm.gz title CentOS-3 (2.4.21-32.ELsmp) root (hd0,0) kernel /vmlinuz-2.4.21-32.ELsmp ro root=/dev/md0 console=tty0 console=ttyS0,9600 initrd /initrd-2.4.21-32.ELsmp.img title CentOS-3-up (2.4.21-32.EL) root (hd0,0) kernel /vmlinuz-2.4.21-32.EL ro root=/dev/md0 console=tty0 console=ttyS0 ,9600 initrd /initrd-2.4.21-32.EL.img _______________________________________________________ Carbon-Copy List: CC Address | Comment ------------------------------------+----------------------------- cgardiner --AT-- readytechs --DOT-- com | Originator Email _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?func=detailitem&item_id=14893> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
