I have learned that the following is useful for debugging "scheduling while atomic" bugs. The respective files are attached:
$ sudo sh -c "echo 1 > /sys/kernel/debug/tracing/options/latency-format" $ sudo sh -c "echo 1 > /sys/kernel/debug/tracing/tracing_enabled" $ sudo sh -c "echo 1 > /sys/kernel/debug/tracing/tracing_on" $ sudo sh -c "echo function > /sys/kernel/debug/tracing/current_tracer" (reproduced bug) $ bzip2 -c /sys/kernel/debug/tracing/trace > trace.bz2 $ dmesg | bzip2 > dmesg.bz2 ** Attachment added: "dmesg output after reproducing bug" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/687599/+attachment/1788176/+files/dmesg.bz2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/687599 Title: BUG: Scheduling while atomic in fuse_notify_inval_entry -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
