It can not boot similar with the initial report here: http://lists.infradead.org/pipermail/kexec/2010-March/003889.html Below is the detail kmsg, tried noacpi, noapic, nox2apic, they all does not help on this problem.

There is no message displayed if dump was not saved successfully

Hi Chao, Recently you put a commit to output various messages related to dump. Today I was saving dump and it failed but there is no message on console saying dump failed. I think we should display a message on console if dump saving failed. Can you please look into it. Thanks Vivek

[Fedora Patch] dracut-module-setup.sh: setup correct system time and time zone in 2nd kernel.
by WANG Chao 31 Jul '13

31 Jul '13

Currently in initrd, hardware clock is always considered to use UTC time format and system time zone is also UTC. Thus system time isn't correct if hw clock is localtime or we're using other time zone in real root. To fix this, install /etc/adjtime and /etc/localtime to initrd. Previously, this functionality was implemented in dracut base module: commit 77364fd Author: WANG Chao <chaowang(a)redhat.com> base: setup correct system time and time zone in initrd But some people complains about a normal boot initrd needs to rebuild every time if time zone is changed. So let's fix it on our side.

[Fedora Patch v3] kernel cmdline: Remove hugepage allocations
by WANG Chao 30 Jul '13

30 Jul '13

2nd kernel has very limited memory. Allocating huge pages will probably trigger OOM. So let's remove hugepages and hugepagesz kernel parameters for 2nd kernel when 1st kernel are using them. If user wants huge pages cmdline in 2nd kernel, he/she can still specify it through KERNEL_COMMANDLINE_APPEND in /etc/sysconfig/kdump. This patch adds a new function remove_cmdline_param(). It takes a list of kernel parameters as its arguments and remove them from given kernel cmdline. update: 1. Add description of remove_cmdline_param() per Vivek. 2. Remove_cmdline_param() will take kernel cmdline as $1, then strip it and print the result.

[Fedora Patch v2] kernel cmdline: Remove hugepage allocations
by WANG Chao 25 Jul '13

2nd kernel has very limited memory. Allocating huge pages will probably trigger OOM. So let's remove hugepages and hugepagesz kernel parameters for 2nd kernel when 1st kernel are using them. If user wants huge pages cmdline in 2nd kernel, he/she can still specify it through KERNEL_COMMANDLINE_APPEND in /etc/sysconfig/kdump. This patch adds a new function remove_cmdline_param(). It takes a list of kernel parameters as its arguments and remove them from 1st kernel cmdline or KERNEL_COMMANDLINE if set in /etc/sysconfig/kdump. However It wouldn't touch user specified KDUMP_COMMANDLINE_APPEND in /etc/sysconfig/kdump. update: Add description of remove_cmdline_param() per Vivek.
