Example panic below. I've bisected it to commit eac3ef262941 ("nvme-pci: split the initial probe from the rest path"). I'm not seeing this on any other emulated platforms that I'm currently testing (x86_64, riscv32/64, mips32/64 and sparc64). nvme nvme0: 1/0/0 default/read/poll queues NET: Registered PF_VSOCK protocol family registered taskstats version 1 nvme nvme0: Ignoring bogus Namespace Identifiers /dev/root: Can't open blockdev VFS: Cannot open root device "nvme0n1" or unknown-block(0,0): error -6 Please append a correct "root=" boot option; here are the available partitions: 103:00000 61440 nvme0n1 (driver?)
