hi guys, I have one rig with 8 x RX580 nitro+ and I am trying to use claymore 11 (the latest version) whenever I start it one of the GPUs has 0.00 Mh/s and gets also an error:

WATCHDOG: GPU 7 hangs in OpenCL call, exit
WATCHDOG: GPU 7 hangs in OpenCL call, exit
Quit, please wait...

I need to mention that on claymore 10.6 all works ok so i do not think it is related to overclocking or undervolting, drivers, bad riser, etc.
I am using linux as OS.

any advices?

thanks in advance
