[pkg-fso-maint] Bug#647277: fso-gsmd: RequestResource GSM fails with "Can't open the modem"

[Niccolo Rigacci]

Package: fso-gsmd
Version: 0.5.0+git20110916-1
Severity: important

Dear Maintainer,
I'm running Debian/Sid on the OpenMoko FreeRunner GTA02.

The first time I request the GSM resource, it works well.

Then I release the resource to save battery; after that,
every GSM resource request will fail leaving the resource
unusable. I have to restart fsogsmd to recover.

Here it is the mdbus2 chat I use:

org.freesmartphone.ousaged /org/freesmartphone/Usage
    org.freesmartphone.Usage.RequestResource GSM
()
org.freesmartphone.ousaged /org/freesmartphone/Usage
    org.freesmartphone.Usage.ReleaseResource GSM
()
org.freesmartphone.ousaged /org/freesmartphone/Usage
    org.freesmartphone.Usage.RequestResource GSM
org.freesmartphone.Resource.UnableToEnable: Could not enable resource 'GSM':
    GDBus.Error:org.freesmartphone.Resource.UnableToEnable: Can't open the modem.


The GSM power is turned-off on ReleaseResource, then it remains
turned-on despite the RequestResource failed.

Here it is the fsogsmd.log:

I have to power down the GSM using omhacks, kill fsogsmd and restart
it; in this way I can re-open the GSM resource.

Let me know if I can help in debugging.
