Description yangtiezhu loongson_group 2024-10-15 11:34:48 UTC 
Description of problem:

In the current code, if the rootfs is located on a SCSI (or NVME) device
and root=/dev/sda3 (or root=/dev/nvme0n1p3) is specified as boot option,
kernel boots failed with CONFIG_BLK_DEV_SD=m (or CONFIG_BLK_DEV_NVME=m)
when there is no initrd with defconfig.


Version-Release number of selected component (if applicable):

6.6.52


How reproducible:

use defconfig to build and update kernel, kernel boots failed if there is no initrd.


Steps to Reproduce:
1. build
2. update
3. boot

Actual results:

  /dev/root: Can't open blockdev
  VFS: Cannot open root device "/dev/sda3" or unknown-block(0,0): error -6

  /dev/root: Can't open blockdev
  VFS: Cannot open root device "/dev/nvme0n1p3" or unknown-block(0,0): error -6

Expected results:
