Hi LKML,
I've got an IDE harddrive in a USB external enclosure. It is /dev/sda.
When I'm compiling the kernel or doing other things on /dev/hda1 the USB
harddrive (sda1) will spin-up or not spin-down. This happens with kernel
versions 2.6.28-rc7 and 2.6.27.8, but not with 2.6.26.8.
Also, I'm using laptop-mode-tools to turn on laptop mode.
I used the "btrace" script on /dev/sda while compiling a kernel on /dev/hda1.
While running 2.6.26.8 btrace did not output anything. With 2.6.27.8 and
2.6.28-rc7 a load of stuff was going on with /dev/sda.
I don't know what it means, but it is probably what is causing the harddrive
to spin up. :) Hopefully someone besides me will consider this
a "regression". Let me know if you need any other info.
Thanks!
C.
Using 2.6.26.8, btrace of /dev/sda while compiling on /dev/hda1
did not output anything.
Using 2.6.27.8, btrace of /dev/sda while compiling on /dev/hda1

This is not a USB issue. usb-storage merely passes on to the device
the requests it gets from higher up. If those requests cause the drive
to spin-up or not spin-down, blame the higher-up subsystems.

I am currently doing recompiles to see when the below problem first showed
up. The change in behavior started somewhere between 2.6.27.5 and 2.6.27.8 .
Eventually I will be able to say that the change occurred somewhere between
2.6.27.n and 2.6.27.n+1. I'm using an old k6 233 mHz, so it might take a few
days!
I am not a kernel hacker, but I would guess there was some change in the
journal code that causes it to "leak" journal commits to a non-active device
when triggered by the activity of another device.

Hi LKML,
The harddrive spin up issue I'm having (described below) does not occur in
2.6.27.5 but does occur in 2.6.27.6 .
One thing I didn't mention in my original email is that both /dev/sda1
and /dev/hda1 are ext3 file systems.
Let me know if any other info is needed,
C.
