I had 2 rigs with Vega 56 cards and both recently stopped working/mining.

When I try to start miner I get following error:

tdxminer version 0.2.2.2
  This is a beta release and may be unstable on some hardware.
[2018-07-16 09:41:00] Failed to list OpenCL platforms.

I did not changed anything on them, so I dont get why they stopped working.


lspci |grep VGA
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 687f (rev c3)

/opt/rocm/bin/rocminfo
hsa api call failure at line 900, file: /home/jenkins/jenkins-root/workspace/compute-rocm-rel-1.8/rocminfo/rocminfo.cc. Call returned 4104

Any solution?
