| It was a couple of problems. First of all, I had my modules file screwed up (which was probably the original problem in the first place). Secondly, all the kernel compiles I'd done had left kernel images all over hell and gone, and I didn't understand that I had to reconfigure grub each time; I thought make install would just replace the old kernel image and grub would use the new one. Oops. I wound up just getting rid of all those kernels, reemerging gentoo - sources (this time without the genkernel; that thing sucks), configuring and compiling it manually (my first kernel roll in 8 years of Linux usage!), redoing the modules file and reconfiguring grub. I'm now sitting here looking at my nice shiny kde desktop. Thanks for the responses! If anyone is still feeling helpful I now can't get my wifi working and have a thread over I. Networking... |

| Hehe, I usually don't add entries to GRUB everytime I need to recompile the Kernel, I just name the new kernel like the old one. |

smlbstcbr,
That works until you make a broken kernel and you can't find a new one to boot with.
Sometimes Linus will make a broken kernel for you.

That's what I do. There are obviously two items in GRUB menu. |
And why you guys keep copying that bzImage at hand... without any version string and proper name? You're looking for BIG TROUBLES or something?! Just asking, no pun or ofense intended. I mean, while you're in `/usr/src/linux' what prevent you to...
| Code: | mount /boot
make install
make modules_install # I guess everyone does this, right?
make headers_install
|
What prevent from just rolling the other essential steps/cmds after building a new kernel?
Just asking.
PS: `make install' will properly install a new kernel `vmlinuz-$KV' and move the old to`vmlinuz-$KV{,.old}'... I guess anybody know this, at least anybody building a kernel at hand and who know what [s]he's doing.

Fine. Lucky you! Well, you may read the previous post of NeddyS before you run out of luck. (pun intended)

I do basically what Jaglover does, and never had any issues due to it. Not sure why I do it; it's just how I always did do it!
I believe the problem NeddySeagoon is referring to is only a problem if one doesn't keep backupses of the old, working kernel(s) that they can boot in case the new one is a doozy. ^^
