I've started a new thread on my kernel troubles. I thought the thread |
| 2 |
subject should be more indicative of the semi OT nature of the query. |
| 3 |
|
| 4 |
Also thought it might make the information that accrues here more |
| 5 |
findable for any future searchers. |

Here is the general setup and the general problem: |
| 8 |
|
| 9 |
vmware appliance made from gentoo-2008.0 |
| 10 |
|
| 11 |
|
| 12 |
I downloaded this appliance from a friendly sight that has all kinds. |
| 13 |
The appliance was built in July and so needed some updating. I |

| 17 |
So cutting to the chase here. All software updated nicely but when I |
| 18 |
started fooling with the kernel I hit a brick wall. |
| 19 |
|
| 20 |
The original is 2.6.24-r8. Apparently built with genkernel as it has |
| 21 |
just about everthing possilbe enabled. |
| 22 |
|
| 23 |
The original setup was rigged to boot with an initrd |
| 24 |
(from grub) |
| 25 |
|
| 26 |
title=linux-2.6.24-gentoo-r8 |
| 27 |
root (hd0,0) |
| 28 |
kernel /kernel-genkernel-x86-2.6.24-gentoo-r8 |
| 29 |
root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sdb3 |
| 30 |
initrd /initramfs-genkernel-x86-2.6.24-gentoo-r8 vga=0x317 |
| 31 |
|
| 32 |
And originally used /dev/sda3 for root. |
| 33 |
|
| 34 |
It worked just fine. But none of my attempts to bring the kernel up |
| 35 |
to date have worked. All failing with a error message something like: |
| 36 |
`/dev/sdb3 is not a valid device'. |
| 37 |
|
| 38 |
But of course it is because reverting to the original kernel allows a |
| 39 |
successful boot. |
| 40 |
|
| 41 |
You'll notice I've since moved root from /sda3 to sdb3... expanding |
| 42 |
everthing. That is not the cause of the problem though since the |
| 43 |
original kernel boots just fine with the edit to /dev/sdb3 as root. |
| 44 |
|
| 45 |
I will post exact error messages in a bit but I'd gotten rid of the |
| 46 |
extra sources.. and was about to give up messing with this. |
| 47 |
|
| 48 |
I'm redownloading the latest gentoo-source and will post what ever |
| 49 |
errors occur with it. I'll build using the old kernel config as |
| 50 |
basis. And ditch the initrd. |

Looks like I fogot to mail the message above so even better... Now I |
| 55 |
have a screen shot of the messages. |
| 56 |
|
| 57 |
I've compiled 2.6.27-r5 using the config that works with 2.6.24-r8 as |
| 58 |
the basis. I did prune out a few things... all wireless some hid and |
| 59 |
most usb. |
| 60 |
|
| 61 |
This kernel fails as I expected and here is small screen shot of the |
| 62 |
error. It appears something is lacking that lets the kernel know that |
| 63 |
/dev/sda1 (boot) and /dev/sdb3 are valid /boot and / |
| 64 |
|
| 65 |
Here are the grub lines: |

title=/dev/sda1 hp 2.6.27-r5 NO INTITRD |
