[Bug 24533] Re: Fail to boot smp kernel

[Richard Green]

I did another full update, which picked up kernel 2.6.15-23-686, so I tried it again.
  Got a bit further.  I booted initially to a console prompt, where I only ran 'cat /proc/cpuinfo' to verify that I was indeed running an SMP kernel (output attached).  Then I issued the 'startx' command.
This time, I got all the way thru the KDE initialization.  I saw the 'KDE is up and running' message just before the central info window disappeared.  Konqueror had even loaded this web page, as evidenced by the button-label on the toolbar, but when I went to move the cursor to select that desktop, I found that the system was indeed frozen solid.
  Is there a way I can turn on some kind of strace or kernel debugging just before I issue the startx command, with its output directed to a serial port where I can capture it on a more stable system?
