Subject: nvme boot problems after merge of mm-stable tree into linux-next
Hi,
I am having problems booting from nvme in linux-next. Bisect points to 06e5887cdcc11
("Merge branch 'mm-stable' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm").
The problem was first seen on February 8.
Some of the log messages as well as the bisect log are attached. Note that the problem
is not seen in all architectures. The list below may not be complete since several
architectures/platforms fail to boot for other reasons.
Guenter
