hi guys,

I have a weird problem i can't figure out.
i have a 5 GPU rig running on windows with claymore 7.4 nicely hashing at 30.1Mh/s
I now want to do the same but under linux using the AMDGPUPRO drivers

all seems fine running ubuntu 16.04
however without overclocking i get these values:
ETH: GPU0 4.176 Mh/s, GPU1 26.804 Mh/s, GPU2 26.776 Mh/s, GPU3 26.778 Mh/s, GPU4 26.868 Mh/s

I tried this with ubuntu 16.04, ethos, simplemining.
They all have the same issue GPU0 is super slow.

I also see the following difference when i check the clocks:

piwi@gpuminer01:~$ cat /sys/class/drm/card2/device/pp_dpm_mclk
0: 300Mhz
1: 2000Mhz *
piwi@gpuminer01:~$ cat /sys/class/drm/card0/device/pp_dpm_mclk
0: 300Mhz
1: 2000Mhz


Any clue how to fix this and gpu0 mining normally, like it does on windows.
It's also not the card, switching cards doesn't help.
