M5 does not love Sigma 17-50 2.8

Hi All,

I have a brand new eos m5. Thru the adapter I have Sigma 17-50 2.8 connected. If its OIS is ON during powering down the camera: the camera freezes for ~2min with black screen (but backlighted). Totally non responsive. To regain responsiveness I can do one of: wait the lag reseat the battery disconnect lens or its adapter. The quiet OIS of the lens is hearable during the lag.

Canon's support blames Sigma. The lens is working fine on my old 550d.

Anybody has EOS M5 and Sigma 17-50 2.8 (or different) combo with similar problem ?
