I tried kdump without acpi_rsdp on your reserved machine. 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.

I tried kdump without acpi_rsdp on your reserved machine. 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.

I tried kdump without acpi_rsdp on your reserved machine. 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.
Hi Dave,
Rich change the motherboard on this system. So looks like new motherboard does not work while old one worked. Strange.
BTW, did you modify kexec-tools on this system to remove "noefi" and "acpi_rsdp=" parameters from command line. Or this kexec-tools is old.
Thanks Vivek

I tried kdump without acpi_rsdp on your reserved machine. 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.
Hi Dave,
Rich change the motherboard on this system. So looks like new motherboard does not work while old one worked. Strange.
BTW, did you modify kexec-tools on this system to remove "noefi" and "acpi_rsdp=" parameters from command line. Or this kexec-tools is old.
Now this system does not seem to work even with acpi_rsdp specified. root device does not seem to show up. I am not seeing any lvm related initialization at all.

I tried kdump without acpi_rsdp on your reserved machine. 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.
Hi Dave,
Rich change the motherboard on this system. So looks like new motherboard does not work while old one worked. Strange.

This system is behaving strangely. Yesterday I tried everything and it did not work and today both 3.9 and 3.10 kernel seem to work (with acpi_rsdp=). I am upgrading kexec-tools now and will try again. If that works, then will try without acpi_rsdp.
Well, with 3.10 kernel boots up device showsup but dump saving fails. Looks like makedumpfile bailed out.
Hopefully upgrading kexec-tools will fix it.

I upgraded from kexec-tools-2.0.3-71.fc19.x86_64 to kexec-tools-2.0.4-5.fc19.x86_64 and memory problem started happening. Have we done any significant change in kexec-tools which contributes to this.

The main contribute is Harald enabled 98selinux. Chaowang said selinux will use ~50M memory as the peak for load_policy. That is too much..
Ccing selinux peole Daniel and Eric. I wonder if there's a way we can use in kdump initrd for minimum memory footprint. Because we will not switch_root, so it will not influence the normal 1st kernel selinux.

Hi Dave,
Have few questions.
- I upgraded kexec-tools package and not dracut. So how did memory usage go up.
- Were we not always loading selinux polity in initramfs. Otherwise I will see relabeling happen when I boot back to first kernel. And In my testing I did not see any relabeling happen. (I will make sure I was not testing with selinux disabled).
- 50MB for selinux policy sounds too much. In RHEL6 this usage was around 30MB and I remember in early fedora days it had dropped down to 18MB. Daniel, Eric, does selinux policy load memory consumption has to be this much. We reserve 128MB and 50MB is a huge chunk of that.
Ccing selinux peole Daniel and Eric. I wonder if there's a way we can use in kdump initrd for minimum memory footprint. Because we will not switch_root, so it will not influence the normal 1st kernel selinux.
I did not understand above statement Dave. Are you saying that we can save vmcore on root filesystem without loading selinux policy and still avoid relabeling in first kernel when it boots back. How?
Thanks Vivek

Should always load selinux in initramfs unless rootfs mounting fails.

Dracut will always mount rootfs so mostly we need not relabel in 1st kernel because chroot load_policy in 2nd kernel will work unless rootfs mounting fails.
I ever tested loading minimum policy in RHEL6, it use much less memory than targeted policy. Our target is simply label like file /sysroot/var/crash/*/vmcore. I'm wondering if there's similar method we can reduce memory usage in capture kernel.

Clarify a bit this, I means if there's a minimum way to use in initramfs to enable selinux without 'chroot load_policy'.
