First, network dies, then the whole system. There are several kernel crashes in the logs. --- snip --- ProblemType: KernelOops Annotation: Your system might become unstable now and might need to be restarted. Date: Wed Feb 10 09:20:35 2016 Failure: oops OopsText: BUG: soft lockup - CPU#1 stuck for 23s! [smbd:5908] --- snap --- Followed by kernel stack traces. After some investigation, it turned out that the crash can be triggered by Samba. It's easily reproducible by running the following commands in the Samba master branch: ./configure.developer TDB_NO_FSYNC=1 make -j test FAIL_IMMEDIATELY=1 SOCKET_WRAPPER_KEEP_PCAP=1 TESTS="samba3.raw.composite" Downgrading to kernel 3.13.0-76 solves this problem. Please let me know if we can provide more information or help testing. Thanks!
