Thanks for that info Jonas. I passed optargs=irq_mode=1 in
/boot/uEnv.txt on archlinux arm (kernel 4.4.23) and verified with
[root@alarm ~]# cat /proc/cmdline
console=ttyS0,115200 root=/dev/mmcblk0p1 rw rootwait irq_mode=1
But it still does not work:
[root@alarm ~]# rmmod ath10k_pci
[root@alarm ~]# modprobe ath10k_pci
[ 28.791404] ath10k_pci 0000:02:00.0: Refused to change power state,
currently in D3
[ 28.829352] ath10k_pci 0000:02:00.0: failed to wake up device : -110
[ 28.835861] ath10k_pci: probe of 0000:02:00.0 failed with error -110
Did i do something wrong? If somehow possible, i would prefer to not
rebuild the kernel and somehow configure the existing one without changes.
Kind regards
Oli

The problem is gone with kernel 4.7.3 on armbian - both compex cards work

Interesting to know this issue isn't present in 4.7 - I also
encountered it in 4.4 with LEDE.
unfortunately that kernel does not support sfp (seems like
its kind of proprietary drivers from clearfog).
They aren't really proprietary, they are proper patches that were
submitted as RFC once, so it shouldn't be much effort to port them to
e.g. 4.7. Anyways ...
So its a driver issue but i
have no clue who to contact or where to file a bug report. The only
available kernel which supports sfp (from solidrun, vendor of the clearfog
board) is 4.4.23
I am wondering if i could simply checkout the 4.4.x sources, merge the
atheros drivers in it and try to rebuild the kernel?
the issue seems to be that MSI interrupts do not work on 4.4 (at least
with ath10k, didn't have any other drivers that support it to test).
Your options are either to disable support for them in the kernel
config, or pass irq_mode=1 to ath10k_pci on probe to force legacy
interrupts; it should work then properly.

Jonas
