I did some further testing with older kernel versions from
snapshot.debian.org to identify from when on the problem occurs and
discovered 2 things:
1) The problem does not necessarily occur every single time. For some of
the affected kernel versions, I needed two or three attempts (with
reboots in between) to reproduce the issue.
2) The first affected kernel version is 4.14~rc3-1~exp1, while 4.13.13-1
still works without problems.
In addition, there is a stack trace posted at
https://lkml.org/lkml/2017/12/17/212 that looks very similar, so the fix
referred to at https://lkml.org/lkml/2017/12/20/426 might fix the issue.
Regards,
Michael
