I make a quick review, use checkpatch and post it.
Thanks for testing and sorry to not always take the time needed to propose a patch to

Seems to be this:
i) When the modem is first powered on, service discovery takes some time (more than 5
ii) The service discovery timeout fires before the QMI request returns so discover_reply
gets called before discover_callback and things get cleaned up
iii) Then the QMI request returns and discover_callback gets called even though the
request has timed out in ii)
...and this is where things go wrong because the userdata pointer to discover_callback is
probably no longer valid.
How do we handle the QMI request returning a _late_ response, i.e. after it technically
has timed out? I'll dig a bit more...
When I look at my personal patches, it seems I've already seen that. Please find
attached the patch I currently have in my setup on this subject.
Yes, that's exactly what I was just in the process of implementing. Glad you beat me
to it. :)
I tested your patch and it solves the problem. Can you submit it to the list? If not, I
I think service_create_reply() has the same issue but I don't hit it in my setup..
Eswaran: try the patch from Christophe... I'm 99% certain it solves your issue.
Sorry, I couldn't able to run GDB on my test bench. So not able to provide the
necessary core dumps. I applied the patch you had provided. This fixes the issue during
enabling the modem.
The ofono process is not getting exited when I run enable-modem.
But I am seeing some other issues. After starting the system ,I am running the scripts
when I identify the modem device and ofono service is in active state.
/list-modems --> here I am checking the ofono sim interface for SIM card status. The
ofono is reporting that SIM is not present even though the SIM card is attached to the
/offline-modem -> the ofono process gets exited.
I have attached the debug logs of ofono. I will try to get backtrace and post as soon as
