I tried with the upstream kernel : nborisov@fisk:~$ uname -a Linux fisk 4.7.0-040700-generic #201607241632 SMP Sun Jul 24 20:34:30 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
In the meantime I managed to find a sequence which can trigger this 100% of the time on the ubuntu kernel. The following commands have to be one after the other: sudo trace-cmd record -p function_graph -l vfs_read -F ls sudo trace-cmd record -p function -l vfs_read -F ls ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605843 Title: Kernel crashes from time to time when using ftrace To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1605843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
