gentoo can't boot after kernel update[solved]

There are two systems for me running gentoo.
And the both met problems.
PC1:
Used to run w/ 945 motherboard and T2500 CPU.
I moved the HDD to a PC w/ GM45 platform and T9400 processor. But it doesn't work.
so I boot from the liveCD and Build new kernel (2.6.33) w/ the original configuration(2.6.30)
But the system auto reboot while booting.

I change the processor configuration to core2 and rebuild the kernel. problem still.

PC2.
It Used to run gentoo w/ GM45platform T9400cpu. kernel 2.6.30
The motherboard is damaged, so I changed the same motherboard.

But when I boot to the system, It's showed need fsck, maybe the time is changed.
I use fsck to check the system, but it crashed my root partition. left the Boot partition w/ older kernel.

I use the latest stage3 and portage, livecd. build new kernel(2.6.34-r1),
But I can't boot w/ this kernel, the problem is similar to the previous.
it auto reboot after
scaning for memory ....
or
simple boot flag set @0x34 ....
or
RPC registeried ...
or type =2000, audit .... inlitialized

But I can boot w/ my older kernel 2.6.30, I've lost the .config file.

What's can I do w/ my kernel configuration?

for PC2:
You say you can boot the old kernel, but lost the .config.

If you have config support in the kernel (most have), then you can get the config from your /proc directory and use it to build the new kernel:

I didn't enable the config support for kernel. And can't get config.gz from /proc

I use the config.gz from liveCD. and build kernel 2.6.33.

But the system hung after show

It's so strange that I changed the BIOS vender from General Software(conquered by Phineox, The embeded BIOS solution) to AMI, and I got the system running OK with all the BIOSes.

What the difference between the two BIOSes is that:
for GS BIOS, the memory address from 2GB~4GB is allocated for PCI address.

The strange thing is not the BIOSes but why the older Kernel , and the liveCD can boot w/ GS BIOS, But the new build ones can't.

I noted there are some options for memory, 3G-1G, 2G-2G,1G-3G. but that doesn't help me.
The pysical memory for the system is 1GB DDR3.

How can I work out why it doesn't work for my newer build BIOS of generl sw

Hi, all,
This issue is reported as a general software BIOS issue, but maybe a bug of new kernel.

I've found other users met the same issue also w/ rhel.

The older kernels before (include) 2.6.30, can support well.

But the newer versions (tried 2.6.33/34), will stop at some line in

It seems the newer version kernels after 2.6.31 encounter issues to support Intel C6 state w/ general software BIOS.

Nice to know and thanks for the informations

Just wanted to let you know that Asus and ATI is not better

I have problems with my Asus Crosshair Formula III ever since I bought it and ASRock BIOS. Cannot Reboot, fails at detecting DRAM and the RAM that is detected is wrong.

Yes, and some motherboards are not tested to support Linux but just windows, that may bring some strange errors.

Why are you using initramfs? It's not needed with Gentoo, unless you absolutely have to have the splash screen instead of the kernel/init screen.

Cheers,
Pappy

I didn't use ramfs. But I have to try the kernel by genkernel. By default, it uses initramfs.

I should have known. There is a better way to set up your kernel. You can use one of my seeds. That means no need for intiramfs, and a better running system.

Click on the link in my sig line, and take a shot at setting a kernel up for yourself. If you'd rather, I can do the job. To do it, I would need the results of lspci -n and cat /proc/cpuinfo as well as your /etc/fstab file, and your current .config (use pastebin, the other link in my sig).

Cheers,
Pappy

Hey pappy_mcfae, Here is the configuration of my homeserver. can you tweak the .config for me? Thanks. The CPU is T2500.

I have posted the .config at http://pastebin.com/4Jy7rVx6

pappy_mcfae · Posted: Fri Sep 10, 2010 9:01 pm Post subject:

Your .config was quite overloaded with unused drivers, etc. The .config I'm sending along started with a fresh seed, and has the newest settings. It should be quite a step forward.

The only question mark I had with your setup was which driver to use for your com ports. The driver I set up is supposedly capable of handling those ports. You might not even use them, but they are turned on.

If you are having stability problems in X, which is likely, I'd suggest moving up to the .35 series, since it is in that version that they finally got KMS to be mostly stable with intel GPU's. Since you have set for KMS, it would be best if you used the most stable version I've found yet, especially if you are having X issues.

Click here for your new .config. Compile as is.

For the best results, please do the following:

1) Move your .config file out of your kernel source directory (/usr/src/linux-2.6.34-gentoo-r1 ).
2) Issue the command make mrproper. This is a destructive step. It returns the source to pristine condition. Unmoved .config files will be deleted!
3) Copy my .config into your source directory.
4) Issue the command make && make modules_install.
5) Install the kernel as you normally would, and reboot.
6) Once it boots, please post /var/log/dmesg so I can see how things loaded.

This is most important. I need to know if everything listed starts properly. Once I'm assured of that, then you should have a very stable system (barring KMS instability).

Cheers,
Pappy

Hi pappy, I have removed some HDA codec drivers left IDT driver and added NTFS support as there is a mobile disk may be attached.

And now I'm making the new kernel. That must be a very stable and fastest kernel for me! I'll post the information later.

Thank you!

Hi pappy, I have posted the dmesg here http://pappy-mcfae.pastebin.com/eBsdzDrX.

It boot very fast, but there are some drv errors with virtual box since the CPU type changed from i686 to P4. Maybe I need to rebuild the VBOX.

For the serial port, I saw there is a line as:

pappy_mcfae · Posted: Mon Sep 13, 2010 6:31 pm Post subject:

According to what I read, the serial ports should be active.

This .config was made to make things work faster. Clearly, that has happened.

As for the the virtual stuff, I would suggest you check the kernel settings against what is recommended to make the vbox stuff work. There should be pages up that tell you which options you need (apart from the seed basics) to add to the kernel to get your support, but not to overload the kernel with unneeded stuff.

Cheers,
Pappy

I reinstalled the latest vbox again and got it work.

I figured that would happen.

Yes, and your kernel seeds do help much to linux newbie like me.

Again, thanks very much for your great help!

You're most welcome!
