Hallo,

I have updated system to xen 4.2.1, linux kernel 3.7.5. System boots
without problem. When I run reboot or shutdown -r now, system correctly
shutdowns all runlevels and then system crashed, see crash_output.txt.
I have the same problem with kernel linux 3.2.37. When I shudown system
(halt), then it is without problem. I have tested kernel 3.7.5 without
xen hypervisor, it was without problems. Required debug informations
(http://wiki.xen.org/wiki/XenParavirtOpsHelp) in attachment.
Could you please help me with this problem?

Thanks

Michal

It's apparently going the triple fault path, and load_idt() under Xen
doesn't do what the code here expects (i.e. that reboot method
just can't work under Xen). Are you overriding the reboot type on
the kernel command line?

The kernel command line from grub.conf

kernel /xen.gz dom0_mem=4G,max:4G dom0_max_vcpus=4 dom0_vcpus_pin
console=com2,vga com2=115200,8n1
module /linux-3.7.5-hardened root=/dev/sda6 console=tty0 console=hvc0

I have not modified reboot type.

And did you check your full boot log for an info-level message like

"%s series board detected. Selecting %s-method for reboot.\n"

I have only checked normal boot log, see attachment in my first mail.
How can I enable info-level message?

The thing is is that native_machine_emergency_restart is not suppose
to be called. The baremetal machine_ops has that, but we over-write
it with our own and he should get:

         .emergency_restart = xen_emergency_restart,

! So how did his .emergency_restart value get over-written by
native_machine_emergency_restart?

Indeed. So perhaps the -hardened tag indicates some patching
having gone on that we're unaware of. Michal - without knowing
what your kernel does, I don't think we can really help. And
please remember that this is xen-devel, not xen-users, so we
expect you to be able to do at least a minimal share of the work
needed to find out what is going on. First step would probably
be to try plain 3.7.5 (or subsequent 3.7.x).

We are using gentoo hardened sources (kernel). Hardened-sources is based
on the official Linux kernel and is targeted at our users running Gentoo
on server systems. It provides patches for the various subprojects of
Gentoo Hardened (such as support for LSM/SELinux and grsecurity),
together with stability/security-enhancements.
See http://www.gentoo.org/doc/en/gentoo-kernel.xml

I will try gentoo-sources (lightly patched to fix security problems,
kernel bugs, and to increase compatibility with the more uncommon system
architectures) and vanilla-sources (official kernel sources released on
http://www.kernel.org/)

Thanks

Michal

The problem was fixed by changing kernel to gentoo-sources. So there is
a problem in hardened-sources.

Thanks

Alpine Linux is also using at least the grsecurity patches and there
seems to be no problem with Xen.
