Hi,
Regarding this issue I have been advised to setup a serial console to capture the 'kernel panic' debug output. For the record, I can get the panic from the BASH prompt _before_ starting X/WM just by mounting my CDRW drive.
However, I think I need some advice on setting up the serial console. I have attached another PC (WinXP with HyperTerminal) serially to my panic Linux PC. Following the Remote Terminal HOWTO I have achieved some success... but all I see on HyperTerminal is:
LILO 22.3.2 boot: Loading Linux_2.4.21................ BIOS data check successful
Mandrake Linux release 9.0 (dolphin) for i586 Kernel 2.4.21 on an i686 / ttyS0 telekon.davesnet login:
It seems to start piping the stuff to ttyS0, but then gives up after a few progress-dots: I'm missing the main kernel blurb (its all on the attached monitor), and also the panic stuff appears only on the attached monitor.
Excerpt of butchered lilo.conf
boot=/dev/hda map=/boot/map #vga=normal default=Linux_2.4.21 keytable=/boot/uk.klt prompt nowarn timeout=100 #message=/boot/message #menu-scheme=wb:bw:wb:bw ignore-table # serial term bits serial = 0,9600n8 image = /boot/vmlinuz-2.4.21 root = /dev/hda3 label = Linux_2.4.21 read-only # vga=788 append = "devfs=mount hdd=ide-scsi console=tty0 console=ttyS0,9600n8"
Any help gratefully recieved!
Thanks
Dave
