Hello,
 I'm trying to confirm hot/warm plugging is working on my system. When
I plug in the drive shows up as expected. I just want to make sure the
stuff I see in the logs is ok.

Thanks,
jason

Hi Tejun,

Can you check these too (I'm testing hotplug on the PDC42819 with ahci driver)?

after powering up eSATA connected drive:

Yeap, looks fine.

Heh.. I usually just pull the power plug doing delete is a good idea.
