BTW: I used minicom to read the console output. Can the problem be related to minicom? It did display grub output though.

Below is my grub setting:

serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
#terminal --timeout=5 serial console
title Xen-unstable / XenLinux
2.6
root (hd0,0)
kernel /boot/xen.gz dom0_mem=512000 console=vga com1=115200,8n1 sync_console
module /boot/vmlinuz-2.6-xen0 root=/dev/hda1 ro console=tty0 console=ttyS0
--------------------------------------------------------------------------
If I enable the "terminal --timeout=5 serial console", I can see the grub interface from the console, but after I chose the boot option,
I didn't further console dump out.
What's wrong with my setting? Help! Please!

Hello,
I am running into xen0 crash. Every time xen0 crashes, it will dump some error messages. Unfortunately, before I can read the details, the system already restarted. Is there anyway to dump the error message to a different serial
console?
How to debug xen0? I mean, xen0, not xen itself.
Please give me some ideas or direct me to the right place to read the documentation.
Many thanks!
