Serious Intel Skylake and Kaby Lake microcode bug unearthed

[peterb]

A question for those with more technical knowledge than me: Can CPU microcode be patched? Or is it purely a case of working around it?

Some Linux systems can load updated microcode at boot time (During the boot process Linux systems generally don't use the BIOS and loads its own code and than can include uploading new microcode - it is volatile so the patch has to be present on the host system). A BIOS update may include patched microcode which again is used during the boot process, but I don't think that there is way of overwriting the firmware in the processor itself as a permanent fix - but Im happy to be corrected on this)

Sounds like a rush job and a serious f-up on the part of Intel, that along with poor reviews of both cpu/ motherboards / overclockers and respected bloggers.............

I'd have to say Ryzen has won me around at this time (and I never thought I'd say anything good for AMD since the 1990's they have been awful).

Maybe thats an indication on how bad this launch has been for Intel?

Athlon 64 was 2003, it was only when Intel launched Core2 in 2006 that AMD have struggled.

Was curious as to the steps involved in Ubuntu

Seems a UEFI update is needed too. Alas, nothing out for my board yet.
