Hi Andy,

I know Takashi in the name of smooth operation usually takes this kind
of simple patch, quickly, since it's a simple bugfix, unless there are
any objections, so I must raise one.

Which HP ZBook? Which model?

Is this a still unreleased model Canonical has had access under a NDA
for example? Or perhaps there is some other reason why you cannot name
the model yet?

Either way, there is a need to publicly know the reason for the missing
model information.

Same questioning as above. "HP" is IMHO unacceptable without a clear
reason for the missing model information.

Thanks,
