Subject: Re: [PATCH 1/3] [v2] powerpc: mac: fix rtc read/write functions
Date: Sun, 1 Jul 2018 18:47:21 +0300 (EEST)	[thread overview]
Message-ID: <alpine.LRH.2.21.1807011844470.19761@math.ut.ee> (raw)
In-Reply-To: <CA+7wUsyN_gru4rW0y3ZzXzYwhfaA=uHKaOG=z5bprnYq6oVfMg@mail.gmail.com>

A patch for the subject is now upstream. That made me finally take some 
time to test it on my PowerMac G4. Tha date is OK but I get two warnings 
with backtrace on bootup. Full dmesg below.
