kdump service will not start
Last modified: 2008-05-06 12:48:03 EDT
Description of problem: kdump service will not start with kernel versions above 2.6.17-1.2174_FC5smp Version-Release number of selected component (if applicable): > 2.6.17-1.2174_FC5smp How reproducible: Always Steps to Reproduce: 1. Boot system with kernel version > 2.6.17-1.2174_FC5smp 2. add "crashkernel=128M@16M" to kernel command line 3. /sbin/service kdump start Actual results: Base address: 125e880 is not page aligned Expected results: Kdump starts. Additional info: I've tried different sizes for the crashkernel option without success.
Looks like this is a problem that all the segments in vmlinux are not on page aligned boundary. Most likely it should be fixed by my patch which is in Andi's tree and in -mm. http://lkml.org/lkml/2006/10/23/289
According to the FC5 kernel changelog, this was fixed. * Thu Sep 28 2006 Dave Jones <davej@redhat.com> - Another day, another round of lockdep fixes. - Align kernel data segment to page boundary. (#206863) However, bug 206863 was opened against FC6, and the current FC5 kernel (kernel-2.6.18-1.2239.fc5.i686) still has the bug.
Sorry, I should have mentioned the latest kernel I had tried this on instead of relying on the date of my post (Nov 13) to be an indication of which versions of the kernel I was talking about. 2.6.18-1.2239.fc5smp has this bug. [root@server1 ~]# uname -r 2.6.18-1.2239.fc5smp [root@server1 ~]# /sbin/service kdump start Base address: 125e880 is not page aligned
