FYI Lenovo has really dropped the ball on supporting Ryzen chipsets for Linux: https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/T...

They simply need to update some entries in bios to fix IOMMU table, but they refuse to do so.

I wish this were true. Even with the kernel parameters listed here: https://wiki.archlinux.org/index.php/Laptop/Lenovo I have an E585 and I _still_ get random kernel lockups (running Ubuntu 19.04). Most of the symptoms I've experienced are listed here: https://bugzilla.kernel.org/show_bug.cgi?id=196683

Such a shame, since the 2700u would otherwise be perfect for my use case :(

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.

I bought the hp x360 2500u when it was about a year old. Took about 8 months before soft lockups stopped on Ubuntu.

A combination of amdgpu kernel ppa and bios updates.

I don't boot into Windows often, but that seems to have got worse.

Linux gets more and more solid, even the touch screen and pen work now, I'm sure the thinkpads will start working in the same way.

These will still be both GPU and CPU on the 14nm process, right?
