Hdapsd lockup (WAS Re: [ltp] HDAPS support for non-Hitachi drives?)

Hi everyone!

I wanted to adress this issue long ago, but that recent mail did the impact:

I also have a A60A version HD from Hitachi, and hdapsd locks up the
whole system from time to time, when active. Otherwise, hdaps itself
(without Head Parking) works without problems, I am using a Kernel
2.6.17.4 on Suse 10.1 with the patches for hdaps and tp_smapi for it.
(But the problem also occured before, with 2.6.16.23).
The drive is in a TP43 2668-F7G, and is the original one that shipped
with it. There was no FW-Upgrade for it available, it seems to be the
most recent Firmware.

The last Kernel-messages are:

Jul  8 16:25:09 tp43 kernel: ata_scsi_issue_protect_fn(): unload support reported by drive..
Jul  8 16:25:09 tp43 kernel: scsi_protect_queue(): head parked..
Jul  8 16:25:10 tp43 kernel: scsi_unprotect_queue(): No pending I/O, re-enabling power management..


What can I do to get a working hdapsd? Is there a chance for it, with my drive?


Thanks in advance,

Armin Hornung
