Hi, we have a AM57xx board here with a PCIe interface trying to access an Intel Wifi PCIe module (8265) running Linux. So far it works, I can find and access the WiFi module, can load the firmware etc. Also performing a scan, connecting to a WiFi access point and performing a PING to a host on the internet works
BUT:
On downloading some data from the internet (sometimes already when performing a ping or when performing a Wifi scan), the PCIe stalls. I can not further access the WiFi card and have to perform a HW reset - the driver just reports a timeout:
The same thing happens with a SparkLAN module (based on Marvell 8XXX PCIe chipset) - it does not report an error but access to the chip via PCIe is not possible any more (lspci -v still shows the PCIe modules but I can not access them any more).
We also checked this behaviour on a Phytec AM57xx eval board - same result.
Hence we think there is an issue with the stability of the PCIe driver.
Is there any known bug / work to do left for the AM57XX PCIe driver ?
Regards,
Sebastian
