Details

Kernels later than LTS fail to initialize Lexar NM70 rendering the drives useless.
This is due to the used Maxiotek (maxio) MAP1602A not correctly reporting its max init time.
There used to be a fallback timeout but it was reduced to 0.
$ nvme id-ctrl /dev/nvme0 | grep -i maxio
subnqn : nqn.2014-08.com.maxio:nvme:1602:M.2:NGJ888R004882P2202

Bug report with patch ("proposed new patch") is here:
https://bugzilla.kernel.org/show_bug.cgi?id=217863

I applied the patch to linux-next and can confirm it works.
I will probably go back to linux or linux-zen, if you want to wait for that.

Thanks!
Andreas

It generally needs to be in some upstream tree before being considered for backport. Is it?

I believe it is still under discussion [1].
