As reported, this is almost a butterfly effect. ->softreset method is
only used during initialization and error recovery of ATA devices which
has almost nothing to do with the rest of the system. This is almost
like 'changing my mixer input to line-in makes power off fail'. (it's
more related due to ATA ACPI stuff and maybe that's why this happens but
I'm trying to make a point here.)
I'm not sure the test can be generalized and included in the firmware
devel kit. This is a really really special obscure corner case bug
which, I believe, none will be able to recreate in the future unless the
same code is reused. So, I think the right course of action is to bug
the manufacturer. Eh.... Does that work with sony these days?
