Hello,
NVMe driver in NetBSD-current was recently tweaked to fix several MP and locking
issues, and the driver is now marked as MPSAFE by default.
Most of this work was done on emulators since I lack the the hardware,
so it's not clear if
everything would work properly on real systems too.
Anyon
I have the hardware and can test this out on amd

Hey,
thank you. This iostat_unbusy panic is typical symptom of the current
MP issues, the command completion queue gets corrupted, and
nvme_q_complete() delivers some commands twice. It causes either this
panic (due to duplicate lddone() for stale buf), or a random kernel
crash.
I've been working
I've now committed my fixes for NVMe driver, should be more stable
now, give it a try.
With those fixes, the driver works without any problem, even under
fairly heavy i/o load, when nvme.c and ld_nvme.c is compiled with -O0,
on both virtual and real MP machine. -O2 kernel works also on virtual
