pacmd running wild 100% CPU when trying to suspend or hibernate

[A. Bram Neijt]

Binary package hint: pulseaudio

On lucid AMD64 alpha 2 (upgraded from a fresh alpha 1 Lucid install) pacmd is now running at 100%. Killing the process will spawn another process of pacmd with the same 100% CPU load. Another inconvenience is the fact that pacmd seems to be inhibiting suspend also.

I've tried killing pacmd mulitple times, but it just keeps coming back with 100% CPU, I finally decided to rm -rf .pulse .pulse-cookie and then kill pacmd and that seems to fix the problem ;)

I've found a way to reproduce this bug, it is caused by suspending. If I try to suspend the system, it will fail and pacmd will go off at 100% CPU. After killing pulseaudio, pacmd is no longer re-spawned.

This issue seems to be connected to suspending in the newest Lucid.

confirmed with lucid i386

This is happening in a 64bit amd version when suspending. Suspend no longer works and shutdown after trying to suspend fails as cpu running at 100%

Confirm that on lucid amd64. strace show only epoll events.
