Workaround(Eee 901 has shutdown problem)

I reported you Eee 901 has "shutdown problem";it sometimes cant cut off the Power and Wifi LED when we shut off Eee 901.
Kobayashi-san pointed out the problem using OpenSolaris on multi-cored PC,you know,he made "usbser" patch for us.so I checked /var/adm/messages on my Eee I found the "WARNING";

so I uncheck "Hyper Threading" in CPU setting of BIOS menu.it works good - it is able to shut off these LEDs.but it is workaround...we cant use "Atom" as "virtual" multi-cored cpu...it is silly..
I told Sayama-san about this problem,he taught me another workaround:),I will try later.thanks a lot,Sayama-san!
