I think Lenovo has a return policy on software that allows you us get
It's worth looking into.

Looks like swapper is swapping where it either shouldn't or couldn't.
It also points to a IRQ which might be shared.
Perhaps a device or driver is acting out of place,
causing trouble where swapper was working.
Did you compile the kernel or did you download it?
Please provide more info about the system,
like /proc/version, /proc/cpuinfo, lspci, free
and a dump of dmesg before and after the BUG occurs.
Remember to http://pastebin.com the info and link it to us.
