Subject: kdump: quad core Opteron
Date: Tue, 07 Oct 2008 18:21:52 +0530 [thread overview]
Message-ID: <48EB5B68.8010401@in.ibm.com> (raw)
kdump on a quad core Opteron blade machine doesn't give a complete
vmcore on the system. All works well until we attempt to copy
/proc/vmcore to some target place ( disk , n/w ). The system immediately
resets without any OS messages after having copied few mb's of vmcore
file. Problem also occurs with 2.6.27-rc8 and latest kexec-tools. If
we pass 'mem=4G' as boot parameter to the first kernel, then kdump
succeeds in copying a readable vmcore to /var/crash.
