I found intermittent instability problems when writing to MPU6050 registers, though reading registers is always OK.

I read the schematic and found the device uses 2k2 pullup resistors.  Since Rpi I2C pull up is 1k5.  So with 2k2 might be too strong, especially I am using long connecting wires.

So I decided to remove the MPU6050’s built in resistors, as shown below.

After the operation, everything seems OK, but of course I need wait longer and see.
