Finally, the KVM hanging issue on E55xx CPUs is resolved with kernel.x86_64-3.10.0-1160.88.1.el7!

Is anyone else experiencing trouble with

I'm seeing a kernel panics in the kvm module on one of our VM hosts with
it.
I did notice a new libvirt update as well, but it seems to work fine with
the
older kernel (.76.1).
Where did you get the .80.1 kernel from? I'm a bit confused because I can
only see .76.1 on my systems.

I'm actually running Scientific Linux, which seems to be a little ahead here.
Probably not related, but vmlinuz-4.18.0-372.32.1.el8_6.x86_64 (AlmaLinux 8.6) had a kernel panic
on a Intel Xeon E5504 processor, but works fine on Xeon E56XX processors (5620 specifically in our
tests). * Believe from kernel version, the original email is for Centos 7, possible the same
change that went into the EL8 kernel went also to EL7 Triggered right after I used virsh start to
start the vm. (Caused Black Screen, and reboot. Found this in the crashed kernel logs on
/var/crash) Works fine on vmlinuz-4.18.0-372.26.1.el8_6.x86_64 and
vmlinuz-4.18.0-372.16.1.el8_6.x86_64
In fact, related - on our systems attempt to start qemu-kvm VM under
kernel-3.10.0-1160.80.1.el7.x86_64 freezes any of 5 workstations with dual E5507 (all worked OK
under kernel-3.10.0-1160.76.1.el7.x86_64 and any previous version). The workstations with E5-2609,
E5-2650 or E5-2630 are not affected - all of them run qemu-kvm VM under
kernel-3.10.0-1160.80.1.el7.x86_64 without problems.
Any ideas?

Petko
