Thanks for the hint. I recently added a pressure and a speed
sensor, using up all two available i2c ports on the board. Looks a
bit like that could have triggered the issue.

I have seen this a few times on Umarim boards. But I think it is
more related to an issue in the i2c driver on the old lpc2148
boards. Unfortunately I never manage to trap the error with a
logical analyzer or a debugger. I don't really know how to search
for it, it is really random.
