FahCore 0xa7 fails on precise-Ubuntu

Posted: Tue Feb 21, 2017 3:07 pm
by suprleg
For several months I've had to stop and re-start my Linux FAHClient in order to acquire a new '0xa4' wu as 0xa7 units won't run and simply fail repeatedly. The frequency wasn't too bad until recently, it's become incessant. Other team members with the similar problem have upgraded their Linux versions of various distros and had success in losing the 'a7.bug', however I'm not wanting to fight with all the reporting scripts at this time.
Has anyone had experience with this error and found a simpler solution?
Thanks for any input.

No, You need at least 14.04 LTS in order for it to work.

I bit the bullet and upgraded to Ubuntu 14.04.5 LTS, a7 wu's are being processed now, thanks for the responses.

There is one recommendation I can make if you are still running the version 7.3.6 client. Upgrade to at least the current release of 7.4.4, or try the public beta. Using the 7.3.6 version your system will not be detected as having an AVX capable CPU, and any Core_A7 WU's will be run using the SSE2 version of the folding core.
