[Bug 53216] Re: BUG() report in getnstimeofday: soft lockup

[John McPherson]

Ok, here is some hopefully more useful information, captured with

$ strace -t -p $(pidof skype) 2>| skype-write-log.txt

just before doing something that outputs sound in skype after it has
been idle for a while. My system hung for 11 seconds, which is captured
in this strace log (although I didn't strace the process from the
beginning, so any initialisation is lost).

The "interesting" call just before the hang is futex(), which is used
for locking in user space. Coincidence?
