<> ||<>|| == Symptom/Bug report == If you see a bug report that says {{{ Corrupted low memory at ffff880000005df0 (5df0 phys) = e47700000000 }}} or {{{ "Corrupted low memory at" kernel warning on resume }}} Most likely this is related to bad bios or buggy bios. == How to Quirk this in kernel. == The fix is to add the bios "vendor" or "board" information to the List of systems that have known low memory corruption BIOS problems. * This list can be found in arch/x86/kernel/setup.c * Scroll down to where it says in comments "List of systems that have known low memory corruption BIOS problems." * You could match by DMI_BIOS_VENDOR or DMI_BOARD_NAME, you need to make the judgment as to which one is appropriate. You can find leads to which to use by looking at what is currently listed. * Build a kernel and get it tested by the originator of the bug. * Submit to Ubuntu Kernel Team and cc stable@kernel.org.
