Description Qian Cai 2010-05-15 02:26:47 UTC
I suspect this is also true for RHEL6.

+++ This bug was initially created as a clone of Bug #522925 +++

Description of problem:
After setting up kdump, if the kernel crashes while the user is operating under X Window, there is no indication of the kdump kernel is in progress. The user would be confused to see if this is a kernel failure or frozen X window. Ideally, the display would switch to the console when the kdump kernel is booting. This problem happens with and without KMS.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. setup kdump.
2. trigger kernel crash (echo c >/proc/sysrq-trigger) from X Window.
Actual results:
No indication of the kdump kernel in progress. Just a frozen X window.

Expected results:
Switch to console to show the kdump kernel is booting.

This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Comment 2 Neil Horman 2010-05-17 12:40:29 UTC
This has been a long standing problem, one which we just can't fix right now.  During a crash there is currently no safe way to return a video card to text mode so that the kdump boot process is visible, or to put up a banner indicating that a kdump is in progress.  The KMS changes make some of this more possible, but only on certain hardware, and under certain conditions.  Its simply to haphazzard a solution to truly be reasonable at this point.
