Dear Linux folks,


Unfortunately, not reproducible, but starting with Linux 6.18-rc7, I got 
the oops below *once*:

```

Please find the output of `journalctl -o short-monotonic -b -1 
_TRANSPORT=kernel` with the systemd entries and systemd messages removed 
attached.

I guess parport is a red hering, but I am not sure, but I am adding the 
memory folks just in case.


Kind regards,

Paul
