Subject: Crash in mlx4 shutdown with 4.9-rc3
Date: Fri, 4 Nov 2016 09:29:47 -0500 [thread overview]
Message-ID: <01e001d236a7$e4c24160$ae46c420$@opengridcomputing.com> (raw)
Hey Yishai, Is this by chance a known bug having a pending fix somewhere? I'm
seeing it frequently when shutting down. I'm using 4.9-rc3 with memory
debugging enabled...
