 |
|
Just tried to upgrade to this kernel because I thought it would fix my 2.6.15 boot segfaults
But this is the error I receive now just after the grub splash.
| Code: |
"Booting 'Gentoo Linux 2.6.15-gentoo-r1'
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /kernel-2.6.15-gentoo-r1 root=/dev/sda3
Error 13: Invalid or unsupported executable format
Press any key to continue...
|
and it goes back to the splash screen.
my grub.conf file is fine as far as I can tell.

Please post grub.conf, your drive/partition configurations, and what you typed at the grub console.

I've already tried to re-create the kernel twice and same error.
All I do when a new kernel comes out, just copy the template three lines, and change the names to suit the new kernel |

| Could it be, that for some reason you copied vmlinux instead of bzImage to your boot partition? |

grub your boot sector again...something might have corrupted it...

| Even if the older kernels still boot perfectly fine? |

| Try rebuilding an older kernel and naming it test in /boot and try booting it. Perhaps it's a compiler chain problem. |

Moving forward on this point, this is an option in my 2.6.15 kernel config:
[*] Optimize for size (Look out for broken compilers!) (NEW)
you could try disabling that. |

Maybe you need to enable kernel support for elf, a.out and ECOFF binaries. Also check if you selected appropriate machine architecture (it may be helpful to post your kernel config). And next time when you want to use your old .config on new kernel remember to run make oldconfig after copying it to new kernel's root directory.

slightly off-topic, but i found no other thread about this: what's better: optimize for size or -O2,-O3 etc?
my cpu is a dothan, so i got 2MB L2-Cache. |

Turns out that I wasn't using make oldconfig correctly, and that I hadn't enabled SATA support 
Thanks for all your help! |
