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

[john]

I suspect Skype is running away (or more likely spin waiting in a tight
loop calling gettimeofday). If a process is SCHED_FIFO 99, then it will
block all other processes from running until it yields. It may be
possible that it could also tickle the soft-lockup detection code. I'm
guessing skype runs suid (in order to set itself SCHED_FIFO 99)? What
happens if you remove its suid bit and force it to run as a regular
user?
