Hi!
I'm trying to create a link to trace a kernel panic so that I can
report a bug with the HP DL 140 server and XEN in opensuse 10.3
But I'm having trouble to set this up. Could anyone please provide me
with a link to a good HOWTO? Google doesn't serve me well (probably
becase I'm do bad queries). I'm running Linux in both ends.
Sounds like you need a null-modem cable for connecting the two boxes,
and then you need to run a serial console on the box that has the
problem. You can do this with lilo kernel
arguments: "console=0,9600,n" - I can't remember the exact syntax, so
look it up. On the other box you run e.g. minicom to capture the
output.

Does the kernel panic occur during the boot process? Is
/proc/sys/kernel/panic_on_oops equal to 1? If it is set to 1, you can
change it to 0, so that you can see the oops message. Have you thought
about kexec/kdump as a way to capture the kernel dump image?
