Subject: [PATCH] kexec: quiet down kexec reboot
Date: Tue, 23 Apr 2019 16:41:54 -0400 [thread overview]
Message-ID: <20190423204154.3085-1-pasha.tatashin@soleen.com> (raw)
Here is a regular kexec command sequence and output:
=====
$ kexec --reuse-cmdline -i --load Image
$ kexec -e
[ 161.342002] kexec_core: Starting new kernel
Welcome to Buildroot
buildroot login:
=====
Even when "quiet" kernel parameter is specified, "kexec_core: Starting
new kernel" is printed.
This message has KERN_EMERG level, but there is no emergency, it is
a normal kexec operation, so quiet it down to appropriate KERN_NOTICE.
Machines that have slow console baud rate benefit from less output.
