Subject: tg3 BUG: spinlock lockup suspected
Date: Wed, 5 Oct 2016 15:06:46 +0300 (EEST) [thread overview]
Message-ID: <alpine.LRH.2.20.1610051502240.23078@math.ut.ee> (raw)
I am testing 4.8 on my sparcs and got this on Sun V210 (sparc64). This
is reproducible. 4.8.0-rc3-00013 did not have this problem, will bisect
when I get some time.
