Hello Alex,
Thanks for replying to my bug report.
I am not certain exactly when this bug was introduced or even which component is involved, but since TF2 was stable a month ago it must be a regression.
I can report that having played well over 2 h with dynamic power management disabled, that this bug is related to dpm.
However, playing with radeon.dpm=1 and setting /sys/class/drm/card0/device/power_dpm_state to 'balanced' (down from 'performance'), the stalls become much less frequent, more in the range of once or twice every 2-3 hours.
I think it's coincidence. balanced and performance are the same on your chip.
