Hello,
I just updated my Debian stretch system using apt-get dist-upgrade to
stretch
9.5, which uses the new 4.9.0-7 kernel. On amd64, the kernel comes from the
linux-image-4.9.0-7-amd64_4.9.110-1_amd64.deb binary package. It was just
released about a week ago. The timestamp on the .deb file is July 6, 2018.
I am running stretch on a Haswell Intel 4590S processor and ASROCK B85M Pro4
motherboard as a Dom0 on the up-to-date Xen 4.8 hyervisor for stretch, or as
a DomU on the same machine and hypervisor for stretch. In both cases, with
the new 4.9.0-7 amd64 kernel, the system enters an endless cycle of kernel
panic -> reboot -> kernel panic -> reboot ...
I also have a Debian stretch 32-bit Xen DomU system and the new 4.9.0-7
i686-pae kernel boots the Debian 9.5 DomU normally on the same hardware.
Only the new amd64 kernel has the problem, not the new i686-pae kernel.
So to run the new Debian stretch 9.5 I need to set grub to boot the
previously
working kernel, the up-to-date 4.9.0-6 version, for amd64. For i686-pae,
I can use the new 4.9.0-7 version of the kernel.
I captured a little bit of what was written to the xen console when the
kernel
panics which is shown below.
Anyone else seen this?
Thanks,
Chuck
