    Hmm. I just noticed the 'perf test' command in 3.2.5. It seems to be a
    much more reliable (or at least faster) way to trigger the soft
    lockups. Testing this on my work laptop for now (I can test on
    something else if needed, but I figured this would do fine).


    On 3.2.5 on metal (perf test -v 3):
    1: vmlinux symtab matches kallsyms:

    Maps in vmlinux with a different name in kallsyms:

    On 3.2.5 under xen:
    snoonan@asmodeus ~/Development/linux-dom0/tools/perf $ sudo ./perf test -v 3

    It hangs after test 3 and then soft lockup messages start spewing out.
    The interesting bit about this is that it does eventually recover -- I
    presume this is because the test is short and there's just really high
    latency on the responses it's waiting for.


    Here's a kernel log I just got for a full 'perf test -v 3' run under xen:
