Hmm, that's strange, I have an Edge 13 machine here, although not the
exact same model as the ones listed in the patch, mine is:

Handle 0x0001, DMI type 1, 27 bytes
System Information
        Manufacturer: LENOVO
        Product Name: 01972NG
        Version: ThinkPad Edge 13"IAL#

and it suspends/resumes just fine.

Manoj, can you send us dmesg and lspci -vv outputs, please?

Thanks.
