It appears that you are right because the following loops incessantly, and only when I go into pm-hibernate, not when I go into pm-suspend. Here is the necessary output: % top PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1589 maitra 9 -11 422m 2176 1048 R 94.9 0.1 8:48.81 pulseaudio % strace -f -s 256 -p 1589 The following keeps on scrolling: [pid 1589] ppoll([{fd=5, events=POLLIN}, {fd=21, events=POLLIN}, {fd=9, events=0}, {fd=4, events=POLLIN}, {fd=20, events=POLLIN}, {fd=26, events=POLLIN}, {fd=31, events=POLLIN|POLLERR|POLLHUP}, {fd=31, events=0}, {fd=30, events=POLLIN}, {fd=29, events=POLLIN}, {fd=22, events=POLLIN}, {fd=25, 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=7, events=POLLIN}], 19, NULL, NULL, 8) = 1 ([{fd=9, revents=POLLHUP}]) Killing pulseaudio (the process) seems to take care of it, and the temperature cools. Once again, I am running the F14-LXDE spin.
