Description Lucas 2016-07-15 04:24:02 UTC
Related to bug #96934, if I try to use a fork of the original mining software, hosted in https://github.com/Genoil/cpp-ethereum (my fork patching it to compile in libclc: https://github.com/lvella/cpp-ethereum) my computer freezes and requires a hard reboot in order to recover. One of the three times I tried, what seemed to be an endless stream of kernel's error log was printed on the screen, but it did not survive in /var/log/kern.log after the reboot.

To try it yourself, download, compile and run:

$ ethminer -G -F mine.weipool.org:5555/0x7079a42c78d28ce9216c290d1bbc61e7b12d54a3/0.5

Note that this is a different OpenCL code than the one in #96934. The code used there is from the official Ethereum repository. This one is from a fork, that seems to be the most used version of the mining software.

Again, that command will mine on the public pool WeiPool and direct the earnings to my address 0x7079a42c78d28ce9216c290d1bbc61e7b12d54a3. If you want to try and don't risk sending me any money, change that number to you Ethereum or Bitcoin address. Instructions in mine.weipool.org.

Lucas, can you retest with current stable or git version? There was a load of fixes on all layers of the OpenCL stack.

Also, according to bug #96934, you were actually able to obtain some performance measurements, does that mean the computer does not freeze right away?

Requested testing was never done, and probably won't be done considering the age of the bug. Closing as the stack has since move on as per comment 1.
