Hi,

would you mind backporting that patch to stables (at least 5.10 and 6.1 are relevant for Debian)?

Thanks in advance!

I have this in dmesg:

[ 0.000000] microcode: microcode updated early to revision 0xa4, date = 2010-10-02

It would be very nice if this message also showed the revision *from* which it was upgraded, so that info is available without going through extra hoops to boot without �code upgrade.

This is fixed upstream in a9a5cac225b0 ("x86/microcode/intel: Print old and new revision during early boot") in 6.3-rc1, but not sure it will have changes to get backported to stable series upstream.

Would you mind trying to get that applied in the needed stable series?
