Hi Martin,
here you are - the second command, however, did not seem to produce
anything useful.
But beware: this is the old firmware, EXT0BB6Q, i.e. the one with the
performance issues (not seen on my machine yet), not the one that causes
the problems with fstrim - named EXT0DB6Q.
As I mentioned I shy away from upgrading at this point, not knowing
whether my Linux system runs fstrim somewhere behind my back. I am not
that deeply involved in the inner workings of the kernel as you guys.
This is my bread and butter machine, I'd rather not expose it to risk if
I can help it.
Cheers
Günter
