Version: 2.6.7-3

Hi guys....
I've got a problem with the 2.6.[6,7] kernels
I'm trying to get this machine running with a serial console
Lilo & the kernel seem to start ok but the whole thing
hangs up just after the root FS mount please see attached

I've attached everything I've captured from the serial console....
PS: Yes, It does work when running the output to the internal VGA console

The above is the last line seen on the serial console....
The system never makes it all the way up!
This machine is destined for a lights out co-location
so access from the serial port is a must have for us :(

Any help would be appreciated

This is not a kernel bug, it's a configuration problem.

Here are the args I pass to 2.6.7 for serial console:
console=3Dtty0 console=3DttyS0,115200=20

Also, my /etc/inittab contains the following:
T0:23:respawn:/sbin/getty -L ttyS0 115200 vt102

Try that.
