any AMD family?</FONT></DIV>

<DIV><FONT size=2 face=Arial>I have server Supermicro H8QGI board and 4 AMD
Opteron f15 processors. Linux won't boot up with HT-ASSIST feature
enabled. No errors... Linux just stuck in some place like this</FONT></DIV>

<DIV><FONT size=2 face=Arial>Also h8qgi buildOpts.c have weird comment about
BLDCFG_USE_HT_ASSIST. It says that this feature don't work in f10 family. So...
does this feature work in any AMD family?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>It's very important problem... because Linux can't
really deal with AMD ACPI SLIT table without probe filter. Kernel code think
that SLIT table is wrong, because it have non-diagonal elements equal to
diagonal (drivers\acpi\numa.c -> "slit_valid" function). So it loads standard
table that produces performance 5 times lower! (in
STREAM)</FONT></DIV></BODY></HTML>
