acpi: freeing invalid memtype bf799000-bf79a000

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi
Since I upgraded to 2.6.35-rc2+ I'm seeing "swapper:1 freeing invalid memtype bf799000-bf79a000"
in dmesg at every boot. dump_stack() in free_memtype() revealed it comes from ACPI.
I thought you might be interested.
