How to capture Kernel Panic messages on serial console?


Hi All,

Due to some NFS bug in RHEL5[2.6.18-92.1.22.el5] kernel, the system panic most of the time....

I have setup serial console, but unable to redirect kernel panic messages to serial port............

I think that you need to configure the serial port as the system console.
http://www.vanemery.com/Linux/Serial...l-console.html

Look at the section called:
Optional: Configure serial port as THE system console

Also look at http://www.tldp.org/HOWTO/Remote-Ser...intro-why.html

It mentions kernel developers using a serial console to be able to capture error messages that flash by just before the kernel reboots.
