+       memory_corruption_check=0/1 [X86]
+                       Some BIOSes seem to corrupt the first 64k of
+                       memory when doing things like suspend/resume.
+                       Setting this option will scan the memory
+                       looking for corruption.  Enabling this will
+                       both detect corruption and prevent the kernel
+                       from using the memory being corrupted.
+                       However, its intended as a diagnostic tool; if
+                       repeatable BIOS-originated corruption always
+                       affects the same memory, you can use memmap=
+                       to prevent the kernel from using that memory.

+                       By default it checks for corruption in the low
+                       64k, making this memory unavailable for normal
+                       use.  Use this parameter to scan for
+                       corruption in more or less memory.
+
+       memory_corruption_check_period=seconds [X86]
+                       By default it checks for corruption every 60
+                       seconds.  Use this parameter to check at some
+                       other rate.  0 disables periodic checking.
