Hi all,
we are running a 4.1 kernel and we have some instabilities using the
8897 over PCIe on an imx7 cpu.
We have observed crashes which look like the logs at the end. I'm not
sure if they are all somehow related.
As already mentioned we are using the 4.1 kernel from NXP with some
patches for the mwifiex driver backported from a more recent kernel,
these additional patches are the following:
* mwifiex: enable MSI interrupt support in pcie
* mwifiex: using right tid for addressing ra_list
* mwifiex: do not short circuit exit from mwifiex_set_mgmt_ies
I know that in the a more recent drivers there were some changes to the
interrupt handling, etc. So maybe there is an issue here. Especially
with MSI enabled.
Anybody got an idea?
Best regards,
Martin
