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, }, -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1811755 Title: X1 Extreme: only one of the two SSDs is loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1811755/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
