Package: pbbuttonsd
Version: 0.7.9-2
Severity: normal
The scripts shipped with pbbuttons will cause it to issue a
hdparm -p /dev/device
(device is typically hda or whatever ide device is there)
I think this used to trigger an "autotune" of the interface, but current
hdparm instead sends the kernel a command to set the drive to PIO 0 mode
instead, which is bogus (it still autotunes if you uses -p 255). It's
not clear whether that is an hdparm bug though. In any case, pbbuttons
shouldn't tweak that setting, the kernel does a fine job on powermac with
IDE settings and should be left alone.
The consequences of the above at this point are to use suboptimal timings
for the command phase of IDE operations and for the data phase of non
DMA commands. However, depending on what kind of IDE patches from Bart
will or will not get merged upstream, this will also cause the kernel
to disable DMA on the interfaces, which is pretty bad.
I would suggest to remove any such attempts at touching the IDE interface
speed settings. ide-pmac get those fine by default in the kernel, there
is no need to muck around.
Ben.
