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? ** Attachment added: "partial strace at time of hang during skype call initialisation" http://librarian.launchpad.net/5134850/strace-log.txt -- BUG() report in getnstimeofday: soft lockup https://launchpad.net/bugs/53216 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
