------- Comment From [email protected] 2016-04-29 05:45 EDT------- At first I reproduced this on kernel 4.4.0-15:
Creating workload: cat /dev/urandom |gzip -9 > /dev/null & cat /dev/urandom |gzip -9 > /dev/null & ping 10.100.86.49 Let PCI device recover: for i in `seq 1 100`; do echo 1 > /sys/bus/pci/devices/0000\:00\:00.0/recover; echo $i;sleep 1;done On the 32nd recovery I got the kernel panic. Retried that and on the 19th recovery the panic occured. Updated system to 4.4.0-22.38 and performed the above steps. Problem did not occur after 2x 100 recoveries. Fix works. Waiting for integration into xenial stream. @Canonical: Please integrate into xenial and yaketty stream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572291 Title: s390/pci: add extra padding to function measurement block To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1572291/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
