Title:
Problems while retrieving SMART information via C602 SAS controller
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi, on my system I get exactly the same issue as reported by Christian Kühnke:
https://lore.kernel.org/all/[email protected]/
When I e.g. run "smartctl -H /dev/sda", my Ubuntu 6.8.0-52-generic kernel
throws:
2025-02-10T14:08:53.031905+01:00 mirakel kernel: sas: Enter

(Also, The SMART output is):
...
=== START OF READ SMART DATA SECTION ===
SMART Status not supported: Incomplete response, ATA output registers missing
SMART overall-health self-assessment test result: PASSED
Warning: This result is based on an Attribute check.
(Expected SMART output):
...
=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED
Christian Kühnke apparently has both identified the cause and the solution to
the bug, which he claims he first discovered in kernel 6.6.62, and is fixed as
of kernel 6.12.11:
https://lore.kernel.org/all/[email protected]/
I suggest the small patch Kühnke suggests is implemented in the Ubuntu-kernel:
