My experience of USB drives is that they take about 20 seconds to come |
| 12 |
up, meaning a root device on one will fail with that error message. |
| 13 |
There are (at least) 2 working fixes that I am aware off. |

The first is us an initrd to delay the mounting root until the USB |
| 16 |
device is available. The second is to pass an argument to the kernel |
| 17 |
that does the same thing, IIRC "sleep=30", but I have never used this |
| 18 |
particular trick, so you will want to check it. |

Either way, my money, based on my experience with using a USB |
| 21 |
hard-disk, is on it being a problem with /dev/sda2 not being available |
| 22 |
at mount. |
