Latest 0.9.21 errata triggers an infinite loop in the pulseaudio daemon. Reproducible when Firefox plays specific effects, under certain conditions. Downgrading to 0.9.19 restores firefox functionality. Version-Release number of selected component (if applicable): pulseaudio-0.9.21-4.fc12.i686 How reproducible: always Steps to Reproduce: 1. Install the Gmail notifier Firefox plugin 2. Configure the Gmail notifier to use /usr/share/sounds/purple/login.wav as the new mail notifier 3. Send yourself a test message 4. Close then restart Firefox Actual results: The first two or three chimes of login.wav are played, then Firefox locks up. Killing the pulseaudio process un-freezes Firefox. Killing the Firefox process instead of pulseaudio pegs the pulseaudio process at 100% CPU, where it remains completely unresponsive: Tasks: 169 total, 2 running, 167 sleeping, 0 stopped, 0 zombie Cpu(s): 25.4%us, 12.1%sy, 2.8%ni, 11.9%id, 47.4%wa, 0.1%hi, 0.2%si, 0.0%st Mem: 2062404k total, 660156k used, 1402248k free, 30820k buffers Swap: 506036k total, 0k used, 506036k free, 428340k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1634 mrsam 9 -11 99.6m 5244 4304 R 95.1 0.3 0:04.43 pulseaudio 1 root 20 0 2024 780 564 S 0.0 0.0 0:01.44 init 2 root 15 -5 0 0 0 S 0.0 0.0 0:00.00 kthreadd 3 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/0 $ strace -p 1634 Process 1634 attached - interrupt to quit ppoll([{fd=4, events=POLLIN}, {fd=40, events=POLLIN}, {fd=33, events=0}, {fd=20, events=POLLIN}, {fd=28, events=POLLIN}, {fd=9, events=POLLIN}, {fd=36, events=POLLIN}, {fd=35, events=POLLIN}, {fd=34, events=POLLIN}, {fd=7, events=POLLIN}, {fd=22, events=POLLIN}, {fd=29, events=POLLIN}, {fd=32, events=POLLIN}, {fd=31, events=POLLIN}, {fd=30, events=POLLIN|POLLERR|POLLHUP}, {fd=30, events=0}, {fd=23, events=POLLIN}, {fd=26, events=POLLIN}, {fd=16, events=POLLIN}, {fd=19, events=POLLIN}, {fd=15, events=POLLIN|POLLERR|POLLHUP}, {fd=15, events=0}, {fd=14, events=POLLIN}, {fd=13, events=POLLIN}, {fd=6, events=POLLIN}], 25, NULL, NULL, 8) = 1 ([{fd=33, revents=POLLHUP}]) ppoll([{fd=4, events=POLLIN}, {fd=40, events=POLLIN}, {fd=33, events=0}, {fd=20, events=POLLIN}, {fd=28, events=POLLIN}, {fd=9, events=POLLIN}, {fd=36, events=POLLIN}, {fd=35, events=POLLIN}, {fd=34, events=POLLIN}, {fd=7, events=POLLIN}, {fd=22, events=POLLIN}, {fd=29, events=POLLIN}, {fd=32, events=POLLIN}, {fd=31, events=POLLIN}, {fd=30, events=POLLIN|POLLERR|POLLHUP}, {fd=30, events=0}, {fd=23, events=POLLIN}, {fd=26, events=POLLIN}, {fd=16, events=POLLIN}, {fd=19, events=POLLIN}, {fd=15, events=POLLIN|POLLERR|POLLHUP}, {fd=15, events=0}, {fd=14, events=POLLIN}, {fd=13, events=POLLIN}, {fd=6, events=POLLIN}], 25, NULL, NULL, 8) = 1 ([{fd=33, revents=POLLHUP}]) ... and so on, to infinity. Expected results: New mail notification plays to the end. Additional info: Rolling back via "yum downgrade pulseaudio" fixes this problem.
