Dear Linux folks,


A disk died on an old system, and is not displayed by `lsblk` anymore 
after a reboot. I would have expected such an event be logged with a 
severe level.

     [   39.816203] ata3.00: disabled

The xfermode message is logged as an error, but I have system, where the 
device is still functional. The actual disabled message is “only” logged 
as a warning.

Is there a way to improve the logging, and log a failed initialization 
of a disk with a higher level? Maybe even critical or alert?


Kind regards,

Paul
