Description Bryn Hughes 2010-02-27 00:21:08 UTC
When booting up my Lenovo W510 I get the message below in my kernel logs:

The system seems to work ok but it does have issues with suspend/resume which may be related.

Lenovo released a BIOS update for these machines earlier this month.  After installing the update I no longer see these warnings.
