Kernel doesn't boot after u-boot I2C device access

Hello all,
I try to read data from an I2C device in u-boot. Right now, I observe a issue in the current version of u-boot-socfpga: https://github.com/altera-opensource/u-boot-socfpga/tree/socfpga_v2020.07

When I boot the device without any I2C command in u-boot, the bootcmd is successfully and the Linux kernel starts.
When I just select the I2C Bus on the u-boot console with i2c dev 0 and then try to boot with run bootcmd the kernel dosen’t start and hangs on the output Starting kernel ...

The device which I use is an Arria10.

Does anyone know how to fix this issue or how to debug it? Right now, I’m quite confused and have no idea where to look in. Is it the u-boot dtb or Linux dtb? Reset sequence or clock configuration…? Or maybe just a bug in u-boot?

=> i2c dev 0
Setting bus to 0
I2C bus i2c@ffc02300 version 0x3132312a
=> run bootcmd

fpga - loadable FPGA image support

Usage:
fpga [operation type] [device number] [image address] [image size]
fpga operations:
dump [dev] [address] [size] Load device to memory buffer
info [dev] list known device information
load [dev] [address] [size] Load device from memory buffer
loadb [dev] [address] [size] Load device from bitstream buffer (Xilinx only)
loadmk [dev] [address] Load device generated with mkimage
For loadmk operating on FIT format uImage address must include
subimage unit name in the form of addr:<subimg_uname>
switch to partitions #0, OK
