Thanks. The first installation was aborted, due to the wrong version of linux-base (>= 4.12 was required, but 4.9 was installed). But after installing linux-base_4.12~bpo12+1_all.deb, the linux kernel 6.15.2 was successfully installed. Yippie. The issue doesn't occur in kernel 6.15.2. As a side-effect, I lost my HDMI display with kernel 6.15.2. According to lxrandr, the display exists and is switched on. But lxrandr could not change anything. Surpisingly, I could move my mouse into the area of the HDMI display (i.e. it didn't stop at the boundary). And therefore my DP monitor was the only available monitor. If I had to guess, I would say, that this kernel relies on newer firmware files, that weren't installed. But I don't know. Thanks for your helpful advice.
