Hello Frederic!
I think, I had a similar problem after an update of Linux Kernel
(without RT). Your effective user id is 4294967295 which corresponds to
-1 if you look at it in 64-Bit-Terms. There seems to be a change of
semantics (-1 changed to 4294967295) in the system and now the rights of
user and the rights of files do not match any more. I can't explain it
any better, but maybe this gives you an advice.
I think, I fixed it by changing the id -1 in the groups or passwd file
to something more sensful ( (unsigned int32)(-1) = 65535 ?).
Have luck!
