Xen Dom0 upgrade gone wrong

[Predrag Punosevac]

Dear Autonians,

It appears that a small group of Alpine Linux Xen users have been able to
locate the offensive patch in two million lines of code which was added to
Linux Kernel between branches 5.15.x and 5.19.x. The current 5.15.62-1-lts
kernel our Xen Dom0 uses appears to be stable. In practical terms that mean
that shell gateway

lop2.autonlab.org

as well as

edshat
tracker
observium
comp
gitlab

are all available and running as expected.

Cheers,
Predrag
