On the 173 page of the second volume biography of the Great Fifth, it states:

There have been many mishaps and disasters at the place. Aiming at these, rituals were performed followed by a wrathful homa rite by the Vajra Acharya Drana Choje (Brag-sNa-Chos-rJe). At the Tantric House of Drepung Monastery, fifty Tantric practitioners from the Upper Tantric College performed propitiation of Shasana for seven days and followed by exorcist rites for five days at Thangpoche. At Songtsen, eight hermits performed homa rites for five days.
 

On the 257 page of above sources, we find the following statement:

It is well known that at Dhol Chumig Karmo a very powerful perfidious interfering spirit (dam si), born due to distorted prayers, has been harming the teaching of the Buddha and sentient beings in general and in particular. The harmful activity has intensified since the fire-bird (year) [1636] and (the spirit) has been successful in many of his missions. But hardly anyone has taken any action, as if this did not concern them. So, at the end of the earth-bird (year) [1648] a new shrine was constructed at Dhol Chumig Karmo and articles were placed there in the hope that it would become a place for the Gyalpo to settle. However, his harmful activities only intensified and recently many lay and ordained people have been afflicted with diseases and a few monks have died. Therefore, all the monks unanimously decided that a fire ritual should be performed. Consequently, two groups of practitioners were organised. One was led by Ngarampa Dhondup Gyatsho, who acted as the Vajra Acharya of (a performance of) the Dorjee Drolo ritual and the other was led by Nangjung Ngagchang Losang Khyentse, who acted as the Vajra Acharya of (a performance of the) Yangsang Karma Dragpo ritual. Likewise Rigzin Pema Thinley of Dorje Drag, Dharma King Terdag Lingpa, Vugja Lungpa, Drigung Tulku Rinpoche, Katshal Zurpa Ngari Konchok Lhundup and Palri Tulku performed the Wrathful Lama, Yamaraja, Phurba, Loktri practice for seven days, at the conclusion of which a fire-ritual was performed during which the 'perfidious interfering spirit' and his entourage were burnt. Many wondrous signs of the spirit and his entourage were burnt appeared.

On the 148 page of the collected works of the Great Fifth, it reads,

Because of the meddling of Lag Agyal of Gekhasa (his mother), the false reincarnation of Tulku Sonam Geleg Palzang (Tulku Dakpa Gyaltsen) got his way and because of distorted prayers he became a perfidious interfering spirit (dam sri) and brought serious harm to sentient beings. Therefore, a total of seven groups of practitioners led by Dorje Drag Tulku Rinpoche ( the fourth rDo-Drag-Rig-'Zin Pema Thrinley), Choegyal Terdag Lingpa, Choeje Vugja Lungpa, Ngari Ngagchang Konchok Lhundup, Palri Tulku and two groups of practitioners of Phende Legshe Ling (Namgyal Dratsang) performed a ritual fire offering and burnt the interfering spirit. This is the testimony I have written at that time:

To the deities, Six Armed Mahakala, Karmaraja and Magzor,

To the oathbound protectors The Four Faced Mahakala, Chamsing Begtse, etc. Who have been propitiated and whose practice (has been done)

I offer this sublime libation.

The so-called Drakpa Gyaltsen pretends to be a sublime being, even though he is not,

And since this interfering spirit and creature of distorted prayers

Is harming everything - both the dharma and sentient beings –

Do not support, protect or give him shelter, but grind him to dust.
