From 4c30c6f566c0989ddaee3407da44751e340a63ed Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Thu, 25 Aug 2011 15:59:11 -0700 Subject: [PATCH] kernel/printk: do not turn off bootconsole in printk_late_init() if keep_bootcon It seems that 7bf693951a8e ("console: allow to retain boot console via boot option keep_bootcon") doesn't always achieve what it aims, as when printk_late_init() runs it unconditionally turns off all boot consoles. With this patch, I am able to see more messages on the boot console in KVM guests than I can without, when keep_bootcon is specified. I think it is appropriate for the relevant -stable trees. However, it's more of an annoyance than a serious bug (ideally you don't need to keep the boot console around as console handover should be working -- I was encountering a situation where the console handover wasn't working and not having the boot console available meant I couldn't see why).
