--- Comment #27 from aaron.hamid at gmail.com ---
I am encountering the same "kernel rejected pushbuf: Device or resource busy"
crash/lock cited here and in
https://bugs.freedesktop.org/show_bug.cgi?id=100567
I'm posting here as I don't see SCHED_ERROR in my systemd journal, and I can
reliably trigger it by running qemu android emulator like kong in
https://bugs.freedesktop.org/show_bug.cgi?id=99900#c24 (so as far as I can
tell, unless resolved android development is dead for me)
