If I use the stock configuration from the 2.6.36-gentoo-r5 kernel, won't |
| 8 |
this have the correct basic kernel facilities built in, at least as far |
| 9 |
as the deprecated IDE capabilities are concerned and the libata |
| 10 |
replacement? I assume the Gentoo devs modify kernels so that the |
| 11 |
default config settings are more appropriate than those which come with |
| 12 |
the vanilla kernel from the kernel devs, yes? |

Putting "root=/dev/sda4" on the kernel cmd line in grub actually worked, |
| 15 |
and got me a bit further in the boot process. The kernel obviously |
| 16 |
understood it. However later in the boot process, I got "Checking the |
| 17 |
root filesystem", following by an error message that the root filesystem |
| 18 |
spec of /dev/sda4 wasn't understood. This is a complaint about the root |
| 19 |
fs spec is in /etc/fstab, since I had been using a UUID spec there, and |
| 20 |
got an error at the same point in the boot-up about the UUID instead. |

I don't know. According to the the ebuild notes with udev, the IDE |
| 27 |
facility in the kernel is completely depricated and needs to be turned |
| 28 |
off entirely to prevent unexpected results. If I build IDE as a module, |
| 29 |
my concern is that the module will get auto-loaded and I'll be back in |
| 30 |
the same boat. So I'll use a more recent kernel and turn IDE off |
| 31 |
altogether and we'll see what happens. |

lsmod will probably give the same useful information. |

Nope. The my rescue CD is up-to-date. |
