Re: Fw: Re: mobile - making a call

No not really ... But there is a good reason the SIM driver is not in master ... it sucks at several level, including blocking behavior in interrupt context IIRC, so it's totally plausible your machine speed triggers some weird things. My advice would be to: - Cleanup the SIM driver - Bypass it in the code and try to access a real PCSC device locally rather than the built in SIM reader. Both are non-trivial of course.
