Hi Juergen, hi all,
Radoslav Bodó reported in Debian an issue after updating our kernel
from 6.1.112 to 6.1.115. His report in full is at:
https://bugs.debian.org/1088159
Note:
We have seen this on 5.4.y kernel: More details here:
https://lore.kernel.org/all/9dd91f6e-1c66-4961-994e-dbda87d69dad@xxxxxxxxxx/
Thanks for the pointer, so looking at that thread I suspect the three
referenced bugs in Debian are in the end all releated. We have one as
well relating to the megasas_sas driver, this one for the mpt3sas
driver and one for the i40e driver).
AFAICS, there is not yet a patch which has landed upstream which I can
redirect to a affected user to test?
Konrad pointed me at this thread:
https://lore.kernel.org/all/20250211120432.29493-1-jgross@xxxxxxxx/
This has some fixes, but not landed upstream yet.
Thanks,
Harshit
Regards,
Salvatore
