I still have this issue with booting, though it seems to be less
frequent. However, I can see in the kernel logs when I boot into linux
successfully that my other drive is being thrown out because of the
duplicate subnqn:
nvme nvme1: ignoring ctrl due to duplicate subnqn
(nqn.2017-12.org.nvmexpress:uuid:11111111-2222-3333-4444-555555555555).
I'm having some trouble testing this on my own since I'm not experienced with
kernel dev, but I wonder if this duplicate entry in the device table in
drivers/nvme/host/pci.c is the issue:
{ PCI_VDEVICE(INTEL, 0xf1a6),
.driver_data = NVME_QUIRK_NO_DISABLE, },
{ PCI_VDEVICE(INTEL, 0xf1a6), /* Intel 760p/Pro 7600p */
.driver_data = NVME_QUIRK_IGNORE_DEV_SUBNQN, },
I believe it should be just
{ PCI_VDEVICE(INTEL, 0xf1a6), /* Intel 760p/Pro 7600p */
.driver_data = NVME_QUIRK_IGNORE_DEV_SUBNQN |
NVME_QUIRK_NO_DISABLE, },
