Dear All,
An update just brought on my CenOS 6 boxes updated microcode.dat files:
/lib/firmware/microcode.dat
Does anybody know off hand what (how critical) is that, as, if it is
related to most famous these days trouble with CPU hardware, I will need
to reboot relevant boxes to have new microcode loaded. But if it is not
that critical, it can wait till next reboot.
Thanks a lot and apologies for laziness (not looking into details of
this particular update myself).
See:

Red Hat have rolled back the recent microcode updates for Spectre as
they were causing instabilities in some systems.
Updated microcode was only made available for a relatively small number
of CPUs so it might be the case that the your microcode was never
actually updated, hence there is nothing to roll back in the latest
release, so no need to panic about rebooting. Checking /var/log/messages
should give you more clues when your microcode was actually last updated
and allow you to determine if it was before or after the recent Spectre
fiasco.
