Hello, Philipp,
Sorry about late reply. There were OLS and then some personal things to
attend to.

When I remove one drive, I get the following messages into

The files /dev/sdb* are removed and the RAID says it has been degraded,
which is perfectly ok.
This looks good.
Now I re-insert the drive and get the following messages into
/var/log/messages:

Hmmm... Softreset fails but libata doesn't notice it has failed.
Can you try the attached patch?
