iPad Pro iPad Pro keeps crashing

[stridemat]

Hi,

My 11” iPad Pro keeps crashing and restarting. I have tried reinstalling iOS and also upgrading to a beta iOS, but to no avail. I have copied the text from what I believe is the associated crash report (panic base) below. Any clues?

[Newtons Apple]

If you reset to factory and your 11” and it is still doing it, it sounds like an hardware issue. Apple should replace the unit.

So I took it back to Apple as 12.1.3 did not fix the issue. They swapped it out for a new one and no issues in the last week. Must have been a hardware issue as you suggested.
