Hi Everyone,

I am not much of a Linux guru, but I am getting the following error at the bootup of the machine. I do not have anything external hooked up to the server(flash drive, external USB, etc. ) Does anyone know why I get this error? This prevents me from logging in and I get a blinking cursor.

Thanks,

-I

/dev entries look okay... any clues in /var/log/boot.log? I'm running low on ideas here...

Are you sure that is the whole dmesg file?
Code:
dmesg > dmesg.txt

post contents of dmesg.txt

Shot in the dark...Try disabling as many devices in bios as possible: mouse, floppy, usb, ethernet, etc.

It is possible that there is so much output from the kernel that the buffer can't contain it all... you would lose the beginning of it in that case. The only way to increase it would be to recompile the kernel. I know in 2.6 kernels there's a CONFIG_LOG_BUF_SHIFT setting that allows you to define the size of the kernel log buffer. I don't know about 2.4 kernels though.
 
Everyone,

Thank you very much for your input on this issue. There was a process which was running in the foreground and preventing the ttys to start. I will try to fix this by making it run in the background and will let you know about the outcome.

Thanks,

Everyone,

Thanks for all of your help. It did indeed turn out that I had a service running in the foreground and preventing the tty from starting. I fixed this by making the service run in the background. It was located in the rc3.d script.

Thanks,
