Ubuntu 启动 busybox initramfs。我试过exit命令，这是结果的最后几行：
Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=9eab400f-420c-9075-b9f395550097 does not exist. Dropping to a shell!
然后再次出现 busybox shell。问题是什么？我该如何修复？
PS： 的输出cat /proc/modules不为空（一些内核模块被加载） 的输出cat /proc/cmdline是
BOOT_IMAGE=/boot/vmlinuz-5.4.0-53-generic root=UUID=9eab400f-420c-9075-b9f395550097 ro quiet splash acpi_backlight=vendor
