Subject: Re: [PATCH RFC] x86: check for and defend against BIOS memory corruption

Out of current discussion I tried using s2ram on patched kernel (I didnot try s2ram earlier, my problem was (un)plugging HDMI - some ACPIcode probably).
Corruption output is quite huge, I attached it to bug report:http://bugzilla.kernel.org/show_bug.cgi?id=11237http://bugzilla.kernel.org/attachment.cgi?id=17526

I do not know much about current discussion and fact if checking forcorruption should be enabled by default.
However, please note that end-user will not able to diagnose thatLinux doesn't work on his machine because of less-or-more broken BIOS.He will not get to know that he needs to enablebios_corruption_check=1 and edit grub to make it default.
I understand that disabling chunk of RAM on every, even not affected,machine is far from perfect, but we have to remember about notadvanced end-users.
