Hi! I was afraid another GSM chip desoldered itself in N900, but no, it seems to be software this time. In 4.4, GPRS is rock solid, can survive overnight ping. In 4.5-rc0 and v4.6, modem fails when I use gprs for like a minute. Phone is not usable.

Phone is not usable. I only send three modem related changes for v4.5: https://git.kernel.org/cgit/linux/kernel/git/sre/linux-hsi.git/commit/?h=hsi-for-4.5&id=525e1abc6b5a7d8bd9006de1da6e99722305ea2b HSI: omap_ssi: fix handling ida_simple_get result https://git.kernel.org/cgit/linux/kernel/git/sre/linux-hsi.git/commit/?h=hsi-for-4.5&id=6bf6ded3008a407ccab5ad72eb59ab71b97cc290 HSI: omap_ssi_port: fix handling of_get_named_gpio result https://git.kernel.org/cgit/linux/kernel/git/sre/linux-hsi.git/commit/?h=hsi-for-4.5&id=403c5c0650816375527a6feecfb255d9b494dda3 HSI: Remove struct hsi_client private fields from kernel-doc The last one only changes a comment, so not relevant, the other two fix error handling during initialization and are most likely also not the problem. Can you try to bisect the problem? -- Sebastian

Can you try to bisect the problem? It will not be fun, but I guess it is doable. But before I start it would be good to know -- does it work for you?

I currently don't have a second SIM card with network access for my dev phone, so I usually only test without gprs connection. As a result I don't really know if longer data connection would work. Also I'm quite busy until next weekend with other stuff. If you did not find anything until then, I will do some testing/debugging. -- Sebastian
