Description

Intel NVMe disks P4510 and P4600 do not work when using ESXi passthrough.
They will immediately marked as faulty.

[[https://illumos.topicbox.com/groups/discuss/T3388f5869edff6a1/esxi-omnios-passthrough-problem-intel-p4510]]

This may caused by the deactivation of MSI-X as described in this [[https://www.illumos.org/issues/9566]]

Is there any chance to get this devices working? Is it possible to get an alternative driver with MSI-X enabled for testing?

Unfortunately, i can not compile a driver myself.

Many thanks for building the test driver.
I have done some tests in the past few days.
The NVMe drive works partially, but there is still the following problem. Parts of OmniOS hang when a normal boot(shut down and start again.) of the OmniOS-VM is performed. The NVMe drive will not recognized. diskinfo or format commands freeze.
When this behavior occurs, I need to reset the VM. Then the NVMe drive will detected.

Frank M. describes exactly the behavior which I can determine now.

Apparently the problems with the NVMe driver exists for a long time and there will probably never be solution for it.

Any news here?

BTW, intel P900 and P905 are also affected.
