Pandaboard does not shutdown properly

[Anton Arnold]

The board still consumes as much power as running after a poweroff/halt/shutdown command.

Last output:
 * Will now halt
[ 1625.254364] System halted.

Power consumption:
Idle: 0.8A-0.9A
After system halt: 0.8A

wifi/eth leds are still on

I found following thread about the same issue: http://groups.google.com/group/pandaboard/browse_thread/thread/b69efbea6655a811

After I connected J6 PIN12 with GND as recommended by the user prpplague, the leds turned off and the power consumption went down to 20-30mA.

It looks like it's an hardware defect or board issue. We might not have any software workaround in kernel. So let me set this issue as invalidate.

[Ricardo Salveti (rsalveti)]

Can confirm this issue with both my A1 and A2 boards.

As from prpplague's (bellow) email this seems this can be fixed by SW, I'm reopening the bug.

"3) complete power off is supported in the mainline kernel and also in the current L24.x omapzoom trees."

PandaBoard currently halts but it doesn't power off as apparently noone is telling the TWL6030 chip to power off. I'd also consider this a bug that should be fixed.

[Paolo Pisati (p-pisati)]

does it happen with latest 3.2 kernel?

[Paolo Pisati (p-pisati)]

no update on this for a while, marking as Incomplete.

[P. S. (sadowsky46)]

I can confirm that it still occirs with the latest kernel

This is working on tilt-tracking about to become tilt-3.4

[Fathi Boudra (fboudra)]

Assign to me for testing once the tilt-3.4 kernel package is available.

Usman is there a point setting importance on bugs we have closed out?
