Subject: perf crash with tip/perf/core
Date: Fri, 3 Jun 2016 18:15:15 -0300 [thread overview]
Message-ID: <20160603211515.GC3095@kernel.org> (raw)
Hi Peter,
I built what is in tip/perf/core to test the topdown patches
from Andi but it is crashing on me, 'perf stat' was ok, but then I tried
'perf trace' and got the NULL deref below, bet 'perf record' will do the same.
BUG: unable to handle kernel NULL pointer dereference at (null)
