0.16.1 reboots machine

[tymoteuszrogalewski]

0.15.8 works stable, but 0.16.1 reboots machine below console logs

can't find the reason, because reboot is so immediatelly. I cant even watch dmesg or other system logs. Adding --no-watchdog not help.

./t-rex -a kawpow -o stratum+tcp://rvnt.minermore.com:4505 -u xxxxxxxxxxxxxxxxxx -p c=XVG -i 20

Two machines with same issues:

• one is ubuntu16, second one is ubuntu18
• both have NVIDIA drivers 450.57
• both have 6x Asus GTX 1070 8GB
• both works stable with 0.15.8 and all older versions of t-rex
• all versions of t-rex cuda9.1/9.2/10.0 tested with same issues.

I'm also seeing many reboots with 0.16.1 whereas previous versions were stable

Try 0.16.2 and start it with --low-load 1 parameter, it will use the DAG generation kernel from 0.15.8. Apparently it crashes during that stage.

0.16.2 with used option --low-load 1 helps. thanks.
