switching XPM firmware back to 3.5.4

Conclusion
It appears that yanking the timing fiber can cause disturbances in the system, but they are not repeatable 100% of the time.
XPMs Power spikes can set the DAQ in a behavior similar to the XPM glitch, but only if pyxpms are running. To be repeated.
Upgrading XPM firmware seems to have mitigated all the issues (to 3.6.0 from 3.5.4). The bucket issue becomes more prominent, probably because other issues are not happening. This issue appears when power cycling the xpm11.
