Hi all,
I started back with the issue and now trying with latest kernel 5.2.7
and still seeing same error "Unhandled fault: imprecise external abort
(0x1406) at xxxxxxx"; though this time it happens in different
conditions as mentioned below (with logs):
If I load the xhci-pci.ko driver, which then wait till timeout and
then gives error -110 (as expected); then after loading the uPD720202
firmware (from user-space utility) I was able to see the USB 3.0 and
USB2.0 devices available through uPD chip (I couldn't connect any
external USB device to it yet as hardware prototype don't have power
support for external devices yet).
Then I did query usb-devices in a loop for 10 mins and it was good.
When tried to reboot Linux then during driver unloading stage saw the
crash from xhci-pci.ko driver (same error as above). So this means it
was working somehow then when doing pci bus shutdown it crashed.
(Didn't have log for it).
Though after reboot tried to load the driver again _without_ firmware
loaded into uPD and got crash number 1 and next power-cycle loaded the
firmware of uPD first then loaded the driver and got crash number 2
(crashes logs are below).
In all crash cases (when loading/unloading the driver); system stays
response, so I can look into any possible device status using PCIe
registers of PEX8605 switch or iMX6 PCIe root hub. Please suggest if
something I can check to better understand the issue.
Have a question that: Can I disable PCIe power management completely
using some kernel CONFIG option OR boot parameter? If yes then how?
Thanks
