That is not directly related to a cache problem. In the past this message
has been frequently caused by cache problems. The messages you're getting
are from kmalloc when being called with another priority than GFP_ATOMIC.
This is illegal because with other priorities the kernel might have to
sleep for example when paging. Interrupts however may not sleep. There
is a zillion other bugs that might cause this.
Who is calling kmalloc?
