Hi,

Microcode update from bug 27597 prevents certain processors in the Intel Tiger Lake family from booting successfully.

MGA7-64 MATE on Peaq C1011 - Intel Atom processor
No installation issues
Rebooted after installation, no problems with different file types, network acess.
Good enough here.

These are all the references in the latest journal after reboot.

At a guess it looks like this hardware is not affected.  It continues to run nicely anyway.

We haven't received complains about this previous update in Bugsquad.
Nor, in MLO french forums.

Also, this update is silently installed on a Intel Core i5 6600K Skylake.
If anyone with a Tiger Lake processor should install this ASAP.

Validating.
Advisory pushed to SVN.

That's because it only affects a subset of Tiger Lake, namely the TGL-UP3 so maybe not many Mageia users even have that hw
