Unfortunately, right after doing a BIOS update on my T520, which has led me into the wrong direction. Additionally, he real colprit is snd.ko, which is loaded as a dependency of snd-hda-intel and - surprisingly for me - thinkpad_acpi. The latter sent me into another round of trying to debug ACPI. I suspected ACPI to be the culprit because my notebook wouldn't suspend. The issue does not appear when one uses a Debian kernel, or uses the configuration that Debian uses for its kernels to build a vanilla kernel.org kernel. This has, after a gazillion of reoboots and experimenting with man different blacklist entries and kernel configuration, led me to the fact that this bug does not show if the kernel is compiled with CONFIG_SND_SUPPORT_OLD_API=y. So it was my error to dump backwards compatibility and to remove the old api support. I have now set CONFIG_SND_SUPPORT_OLD_API=y again and everything is fine.
