Subject: 4.1-rc6 radi5 OOPS
Date: Wed, 03 Jun 2015 16:20:21 -0400 [thread overview]
Message-ID: <wrfjlhg0mtmi.fsf@jes.lga.redhat.com> (raw)
Neil,
I was running testing on the current 4.1-rc6 tree (Linus' top of trunk
8cd9234c64c584432f6992fe944ca9e46ca8ea76) and I am seeing the following
OOPS which is reproducible.
It shows up when running the mdadm test suite, 07changelevelintr to be
specific.
Is this something you have seen?
Cheers,
Jes
