Red Hat Bugzilla – Bug 804836
Kernel trace dump on bootup
Last modified: 2012-04-04 07:10:08 EDT
Description of problem:
A freshly installed Fedora 17 beta install on my Toshiba Satellite laptop throws a kernel dump when booting after initializing the swap but before mounting my /home partition.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora 17 Beta TC1
2. Select standard boot option
3. Wait until mount space is loaded
Kernel error as reported below
System should begin first boot
Linux 3.3.0-0.rc7.git0.3.fc17.x86_64 from the image dated 07-March-2012
Output from kernel seems to begin with these lines, where I haven't copied the time stamp after the first line

And so on. I can reproduce and send further data if it would be of any assistance. This appears to be a regression since Fedora 16, which ran on this system fine until 2 days ago when I tried to do a fresh install of Fedora 17 beta.
we need the whole trace.
Any suggestions how to accomplish that short of copying from one screen to the other by hand as the above partial output gives? Would that be logged to /var/log somewhere?
take a photo of the trace with a camera ?
the kernel kdump feature *should* work in f17, but requires some setup, we're working towards making that easier.

I have attached pictures of the dump starting from where the Bug is first detected and continuing down through the point where bootup is stalled. This is after updating to the Beta RC dated March 23.
