Yeah, I can see that an *extended* period of disconnection can be very problematic with the current implementation.
See, details are very important in problem reporting... I was also able to reproduce the problem with scaling after hours of head-scratching.
Hopefully I will push fixes later today.
On a more positive note, remote monitoring with an sgminer-compatible API is coming soon.
I was finally able to have Awesome Miner recognize GGS.
One last thing. Vega 56 arrived at last this afternoon. This means that Vega cards will get the same level of optimizations as RX [45][78]0.
you need to check whats the difference between blockchain driver and 17.10.2 and later, how they are working with vega
one importand thing i noticed it with a 56vega flashed with 64 bios is(maybe it helps)
-blockchain driver detects this vega as vega 64
-17.10.2 and later detects this vega as vega 56
-speed on most algos is the same on both driver except cryptonight
blockchain around 2000hs
17.10.2 and later around 1400hs
regarding to amd devs vega should switch to workload mode automatic, seems not to work with cryptonight on 17.10.2 and later
