The issues are reportedly impacting Linux distributions such as CentOS, Ubuntu, Fedora and Arch.
Detwiler Fenton has heard that AMD targeted high-end gaming companies using Linux to test the waters on Ryzen before expanding to Windows in the future. The idea behind the strategy, Nenni says, would be to target users that are most likely to have demanding workloads to identify any potential performance problems.

AMD is reportedly aware of the issues and has asked customers not to “open new tickets” related to the problems. Detwiler Fenton noted a software revision could create a fix.
The worst-case scenario for AMD would be an expensive chip re-spin, which would take up to six months to complete and would likely be an expensive process, Nenni said.
