Tail of strace
Description of problem:
Firefox on F20 Alpha RC4 LXDE image locks up when attempting use menus.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Use the Fedora 20 Alpha RC4 LXDE image in QEMU or any ARM device.
2. Start Firefox and try to use any menu or right click for a context menu.
Browser will become unresponse.
While stracing firefox last entry:
futex(..., FUTEX_WAIT_REQUEUE_PI_PRIVATE, 3, NULL, ...)
I was able to get firefox to work by uninstalling all of pulseaudio.
NOTE this required using 'rpm -r --nodeps ...' to ignore dependencies, potentially causing instability for other software that links to the PA libraries.
Worth mentioning that in LXDE the pavucontrol program was also not working.
This indicates a problem with PA in this desktop spin on ARM.
Tested using Compulab Trimslice (tegra2).
I've got debug packages installed if a back-trace is desired?
Resolved in Fedora 20 Beta TC2 for ARM.
Closing this bug for now.
