Comment 85 for bug 177895

It's quite new machine, manufactured in february this year. Maybe there were some minor changes in architeture without noticing anynone..
My model is 7664-RWU - (its specs - http://www-307.ibm.com/pc/support/site.wss/quickPath.do?quickPathEntry=7664RWU + 2g ram more)

Bios update was made due to.. big amount of wakeups, and fan working on and on with ac plugged in.. This fan issue still occurs but after 3 weeks i'm used to it..

Let's try to reset bios settings, but AFAIK the only changed thing was support for VT couse I'm using it quite often, and it is not enabled by default (strange.. )

I didn't installed any older ubuntus here.. No idea about that, but will try to set up 7.10 on external usb disk for some testing..

Little bit similar hardware (but older) - http://www.klabs.be/~fpiat/linux/debian/Etch_on_Thinkpad_T61.html with 1M interrupts on one core vs 7M I have right now..
