Subject: linux-5.1-rc3: nvme hv_pci: request for interrupt failed
Date: Wed, 3 Apr 2019 17:38:04 -0700 [thread overview]
Message-ID: <FCE231C24CDC4243982F7030CC75E92F644C034C@FMSMSX102.amr.corp.intel.com> (raw)
When two nvme devices are discrete-assigned [1] to a linuxvm on
hyper-v rs5 host, it fails to initialize both. It worked a couple of
times and after some reboots it failed. `dmesg` shows:

Device is intel ssd p4608 pci nvme, that consists of two nvme devices
as seen by linux (5.0.1-rc3). Some info from `lspci -v`:
82c6:00:00.0 Non-Volatile memory controller: Intel Corporation Express Flash NVMe P4500/P4600 (prog-if 02 [NVM Express])
8f8d:00:00.0 Non-Volatile memory controller: Intel Corporation Express Flash NVMe P4500/P4600 (prog-if 02 [NVM Express])
Let me know if other info/logs are needed.
