I had ordered an e585 since it was cheap, but cancelled it instead for an e590 as soon as I learnt about these issues. In recent years, lenovo has dropped linux support for the e series, presumably as a cost cutting measure. e570 was the last one to be officially supported by lenovo for linux. Note that the ones that are officially supported such as the T/X/P series ones also often have problems to varying degrees. So with something not officially supported and broken, there is almost zero chance of lenovo fixing anything proactively. The intel variants of e-series (e580/e590) still work about as well as the intel variants of t/x/p. For amd, only A series is officially supported.
