Hi Keith,
I'm still stuck with the 4.4.x tree, which is starting to be a problem as
more fixes for btrfs and others are being rolled into newer kernels.
I realize that I'm in a bad place since this problem seems to be impacting
virtually no one as laptops that boot off nvme are likely rare, but is there
any chance this will get fixed somehow?
More importantly, do you have access to a thinkpad or other laptop with NVME
M2 for testing?
Thanks,
Marc
