Mobile phone hands after 'shutdown now' from the command line

My instance of the Neo hangs if I send 'shutdown now' via ssh. It should
shutdown normally instead (it is rather convenient to turn it that way). The
reboot command works correctly.

The phone hangs when the shutdown progress bar goes over almost full length,
several pixels remaining. It is not responding to power button any longer and
the only way to bring it out of this condition is to remove the battery.

I can see this too, here's the stack trace that gets printed on the UART1 in qemu:

Unfortunately I won't have time to debug this this week, and perhaps effort
should be concentrated on fixing 2.6.24 instead.

  • Severity changed from normal to trivial

Another command, poweroff, does turn the phone off. Hence the principal
possibility exists and likely something minor should be fixed. Well, the
severity is likely really not horrible, reducing it to trivial.

Does this still exist on 2.6.24 based kernel for GTA01?

  • Status changed from assigned to closed

shutdown -h now works on gta01 with daily image from testing repo.
