Subject: Undoing 'quiet' kernel command line option after boot?
Date: Tue, 8 Oct 2013 16:23:59 +0300 [thread overview]
Message-ID: <20131008132359.GX7782@lakka.kapsi.fi> (raw)
Is it possible re-enable more verbose kernel logs/printk's to default
console after boot is done from userspace?
I have a system with correct serial console setting on kernel command line
but there's 'quiet' as well to make the boot faster. After boot I'd like to
run some tests on the platform but would like to get more verbose kernel
messages displayed on the same serial console so they can more reliably be
captured on another PC in case something blows up with trinity etc.
Tried to search /proc and /sys and kernel sources but didn't find anything
related yet.
Thanks,
-Mikko
