SubjectRe: [PATCH] x86/AMD: Apply erratum 688 on machines without a BIOS fix

Sorry for the late reply! This machine has caused nothing but trouble.
HP will not fix it and we will not choose their laptops anymore...

My brother told me that we apply a quirk to the last Ontario APUs that
do not need it but I did not think it would be an issue since they have
fixed the error.
It seems better this way so that only affected APUs are patched. Be
patient, we are compiling the new patch right now but compiling is run
on a different high end AMD machine of my brother. Tomorrow I will have
access to the laptop and I will update the kernel and send you the V2
patch. Compiling to that laptop would possibly need a whole day even
with AC power!


Do you want /proc/cpuinfo on the V2 patch e-mail? Both CPUs needed?
Here is a dump from an older installation some months ago I kept on my
disk(tomorrow I will dump it again if you want):

> Then, keep that *whole* changelog above when sending v2 of the patch
What do you mean? It is not clear to me, Do you mean all the info we
wrote on the e-mail, your comments or both?

We have many AMD machines and we will need your help next week to patch
our Phenom(tm) II X6. Let's finish this
patch first and we will fix that too but it appears to be much more
difficult...
