Date: Wed, 9 Jun 2010 22:09:10 +0200 From: Marcin Slusarz <marcin.slusarz@...il.com> To: linux-acpi@...r.kernel.org Cc: LKML <linux-kernel@...r.kernel.org> Subject: acpi: freeing invalid memtype bf799000-bf79a000 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.
