[OpenIndiana-discuss] Diagnosis help needed

[Mike La Spina]

The error reported task_file_status = 0x4041 on port 3 is a result of an
ATA response where the PxIS.TFES bit was set. The ahci driver must do a
port reset at that point. The SATA disk failed to perform an operation
and reported it. I suspect this is not a data error and may be more on
the lines of a firmware fault on the SATA controller. So it may well be
a faulty disk in the most unruly way, that is conditional e.g. could be
anything around or on the ATA chain, a bad cable, running to hot,
interference, mobo firmware ... etc.

Apologies,

This went to an individual rather than back to the group.

Thanks for the response.

The thing that set of major alarms in my head is the fact that these
errors caused OI to freeze up to the degree where it needed to be
powered off. It would acknowledge the power switch instruction, but
wouldn't power down.
