[2022-01-11 20:52:21] File system error reading verthash.dat
[2022-01-11 20:52:21] FAIL: verthash algorithm failed to initialize

But verthash.dat exists in miner directory.

The error means the file was found but wasn't readable. It may be corrupt, delete it and recreate it.

JayDDee commented 2 years ago

Correction, I have reproduced it. Do you have huge pages?

JayDDee commented 2 years ago

I found the bug. If huge pages aren't available memory allocation fails. It works in v3.19.2, will be fixed in v3.19.4.

JayDDee commented 2 years ago

cpuminer-opt-3.19.4 is released, please retest.

JayDDee commented 2 years ago

No problems reported, closing.
