[Bug 1913866] Re: intel-microcode 20201118 bump request

[Henrique de Moraes Holschuh]

Unless you want regressions on Skylake D0 and R0 for users that are
running with severely outdated firmware, please refer to the
3.20201118.1~deb10u1 of the microcode update.

Keep the microcode for signatures 0x406e3 and 0x506e3 at revision. 0xd6.

Otherwise, it can hang systems where the firmware has versions older
(lower) than 0x80 of the microcode.

The proper fix for this is to detect and refuse the update in the
kernel, but there is no such patch available yet.  Assuming it is not
fixable in a future microcode update.
