Hi Marc,

sorry for the confusion.

The most important patch is for the erratum #89. I don't know why this patch isn't included if 'CONFIG_K8_REV_F_SUPPORT == 1' . Linux Kernel 2.6.12 hangs if errata#89 is not fixed, Kernel 2.6.26 doesn't. 
I'll fix errata#89 and (errata#169 (in place of errata#131)) and (errata#254 if TURION-S1G1), ok ?
Setting of F0x68[22:21] to 01b in 'k8_optimization()' , any idea for a better place ?

Hi Josef,

Thanks for the patch. I have some questions.

It looks like this patch mixed errata #131, #169, with #254.  The rev
guide says to only implement #131 or #169, but there isn't a CPU
version decadency on either of those errata.  The main part of your
patch, the S1G1 checking, looks like errata #254, which is not related
to #169 or #131. Can you confirm that?
