Subject: [dpdk-dev] [4.4 kernel] kni lockup, kernel dump
Date: Tue, 12 Apr 2016 17:19:39 -0700 [thread overview]
Message-ID: <CANmyKO5bLFZA=o=K5wWdvKkzd_epy_2uriH8QqCdsMTFuuCEtg@mail.gmail.com> (raw)
Hi,
I recently upgraded my debian/jessie to 4.4 kernel, and my application uses
kni to
create test interface,
However, when doing 'rte_kni_alloc()', i observed the following log in
syslog...
If i go on trying setting interface via ifconfig, the execution locks up...
