Pass the following in to your kernel parameter list console=tty0, console=ttyS0,115200
Then connect a serial line to your serial port and to another machine and Look at the serial output with hyperterm or something. I didn't want to Do this at first, but it has made my life sooooo much easier. If you can't Do this, consider also that 2.6 kernel has netconsole. Netconsole can Send the same serial information over the network so you can see what is Failing. -----Original Message----- From: zhu shi song [mailto:[EMAIL PROTECTED] Sent: Friday, September 03, 2004 9:25 AM To: Dave Aubin; [EMAIL PROTECTED] Subject: RE: use ramdisk as root file system I've made one initrd to try.
