Ok! Will try asap.

Yes, I have also seen it when just running the commands in the original commit message [1]:
# echo on > $(find /sys -name control | grep \/5600) # rwmem 0x5600fe00 # OCP Revision 0x5600fe00 = 0x40000000 # echo auto > $(find /sys -name control | grep \/5600) # rwmem 0x5600fe10 # rwmem 0x56000024
But I have not yet tested with 5.4-rc2, just 5.4-rc1.
BR and thanks, Nikolaus
