Message-ID: <20190529151003.hzmesyoiopnbcgkb@aura.draconx.ca> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: NeoMutt/20180716 Sender: linux-nfs-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-nfs@vger.kernel.org Hi, I upgraded to Linux 5.1.5 on one machine yesterday, and this morning I happened noticed a large amount of backtraces in the log. It appears that the system oopsed 62 times over a period of about 5 minutes, producing about half a megabyte of log messages, after which the messages stopped. No idea what action (if any) triggered these. However, other than the noise in the logs there is nothing obviously broken, but I thought I should report the spews anyway. I was running 5.0.9 previously and have not seen any similar errors. The first couple spews are appended. All 64 faults look very similar to these ones, with the same faulting address and the same rpc_check_timeout function at the top of the backtrace.
