Incorrect PoC2 file if using multiple output

[zohead]

If I use gpuPlotGenerator in multiple output files mode:

gpuPlotGenerator generate direct /path/123456_0_8192_8192_2 /path/123456_8192_8192_8192_2

then probably only the last plot file will be correct, other files will not be the same as single file mode.

gpuPlotGenerator generate direct /path/123456_0_8192_8192_2
gpuPlotGenerator generate direct /path/123456_8192_8192_8192_2

In this mode, both two plot files are correct.

This happens in Linux with AMD RX 470 GPU card, if I switch to RX 260x GPU, this doesn't happen.

Also if I generate two PoC1 files by one command, then both two PoC1 plot file are correct.

BTW, my devices.txt config is like:

0 0 8192 32 8192

If I change device config to:

0 0 512 32 8192

then gpuPlotGenerator plot multiple files by one command, all plot files are correct.

did you find the reason why it is wrong with AMD RX 470 GPU card ？
