When booting our kernel in blob (using the build and boot instructions given on the web and at
http://projects.buici.com/) we get the following errors:
Bad page state at free_hot_cold_page (in process 'swapper', page c026ec60)
flags:0x00000080 mapping:00000000 mapcount:0 count:0

We are relatively new to this. Do these errors imply that we have bad HW?
Thanks.
