Hello Jocelyn,

My worry is if this could cause other issues so I would only do this change if (is_kdump_kernel()), to make it as non intrusive as possible. And also add a verbose comment about why this is needed.
This change must be done in the "first" kernel, so that when kdump starts, it doesn't hang the machine by writing to the VGA interface, in the early boot code.
Ah, got it. The patch then makes sense to me as is in that case.
My comment about documenting why this is needed still applies though.
Best regards,
