Hi Thomas,

Here you go... The patch applied cleanly against 6.9.3, which I saw was just released by 
Greg, so I used that. If you want, I can repeat the test against 6.9.2, too.

Please note: to be able to boot any kernel >= 6.8.4 on my machine, I also had to apply 
this patch by Martin Petersen, fixing another (unrelated SCSI) regression I reported some 
time ago, see here:

https://lore.kernel.org/all/20240521023040.2703884-1-martin.petersen@oracle.com/

But I think these two issues are not connected in any way. It was during testing the above 
patch by Martin that I noticed this new issue in 6.9 BTW.

I have attached resulting file dmesg_6.9.3-dirty_Bad_wDebugInfo.txt, and I hope you can 
make some sense of it.

Beste Grüße,
Peter Schneider
