Software - Also Kernel 3.12 fails to start

Post subject: Also Kernel 3.12 fails to start
As I wrote, none of the 3.11 Kernels were starting on my machine. I hoped the update to Kernel 3.12 would solve the problem. I deleted the 3.11 Kernels, but that did not help.
3.10 bootes fine, but when booting with 3.12 the message "loading ... " does not appear and the computer stops.

Any ideas?

Like already mentioned before, this is quite a bit too vague to comment upon. What you can try, is dropping the 'quiet' boot parameter from the kernel's cmdline. Doing so should give you more debugging info, which might help to identify the problem.

Given that you have an intel notebook with nvidia graphics, it might also be the case that the modeswitch invoked by loading the kernel support for your graphics card might misdetect the primary graphics card and switch over to the (dormant?) intel graphics. Try to find according firmware settings and/or test what happens if you also connect an external monitor and/or hit the monitor toggle hotkey.

Thanx. I try that report and about the results.

I removed the "quiet"-boot parameter, but it did not help, as it seems, that the very first steps in booting the 3.12 kernel are not reached. I get no messages!
Can there be something with the nvidia graphics, if everything works fie withe the 3.10 kernel and an updated aptosid?
Is it possible to erase and reinstall grub or is this to dangerous?

Maybe you have the same problem:

Thank you debaba, but that seems not to be the problem. I reinstalled grub-pc and reconfigured it, which did not help. I removed the quiet parameter and get some output. Where do i find the output so i can post it here for analysing.

My problem is still unsolved. Maybe this helps: After removing the quiet option, i see, that the startup-process ends with

IMA: No TPM chip found, activating TPM bypass

If the tpm module is acting up (but that message is normal, happens on all systems without a tpm installed), it may timeout for up to 6 minutes - so please check if it makes a difference to let it sit for around 10 minutes.

Unfortunately, that did not work. I waited for about 30 minutes, but nothing happened.

Is there a way to completely remove the new kernel and install it from the scratch?

Thanx anyway

Post subject: What are safe settings?
As I still need a solution for my boot problem, started the latest siduction live cd with a 3.12 Kernel. The standard Kernel did not boot, so i tried safe settings and the system booted. Maybe this is a hint for solving my problem? Does anyone know, what these safe settings are?

In the meantime I found out, that linux mint and opensuse do not start with the standard kernel 3.11. opensuse starts with safe settings ore no acpi, siduction too starts with no local acpi.

Any ideas?

acpi=off solves my problem.

Post subject: RE: What are safe settings?
acpi=off is dangerous and must never be used, not even for temporary testing. Modern hardware absolutely hard-depends on ACPI being available. Disabling it not only disables any but the first core, it may also disable overtemperature safeguards and similar protection methods, which may result in physical/ permanent damage of your hardware.

Post subject: RE: What are safe settings?
Yes, I learned, that this is only ther cause and not a solution. Sound, and other things are not working. So back to kernel 3.10.

Is there a chance, that kernel 3.13 is solving my problem?

There is always a chance, but given that I'm lacking information what actually fails, it's pure guesswork.

Have you tried it with an external monitor in the meantime as slh suggested in the first response?

Linux takes the ACPI settings from the BIOS just as Windows does, but that doesn't work in all cases. On my laptop (which is also nvidia+intel setup) for example I need to force a different OS identifier for ACPI to make e.g. backlight setting work (dmesg is still includes a few messages about buggy ACPI) as the kernel has no built-in workaround for it.
[and no, I am not telling, as I don't consider this safe either]

Stuff as "silly" as upgrading your BIOS might work. But you are probably better of searching on the web for your exact laptop model. It's likely someone had this problem before you and solved it somehow. It's at least how I "fix" these kind of problems.

You should submit a patch. Wink

Yes, but not before I have established world-peace by leading the invasion of earth by my friendly martian brothers. Wink
(I know how the patch would look like to do what I do "by hand", but while I can read the kernels C code, I am bad at reading the decoded assembly of the proprietary BIOS (in all 10 versions shipped so far), so I have no idea what it does – and while I am fine with frying my own system, I would need to do deeper analysis before I potentially destroy hardware of other people)

Yes, at least if you consider the guy not giving the sharp knife to a toddler to be the poopy.

But as you insist: https://github.com/torvalds/linux/blob/ ... osl.c#L109
This enables potentially code paths in the BIOS which NOBODY tested, so anything could happen from nothing over hardware damage to the uprising of the machines against the weak humans!

I have been in that same boat. I gave it a shot in regards to the GPU fan control and the keyboard backlight for my laptop. I even got as far as creating the email. In my case, I was not confident because my own ``fix'' was a mystery to me. It worked, but if someone was to ask me how, I would never return an answer.

This sounds like a wonderful conclusion to the beautiful and peace filled story that has been humankind. I welcome our Linux powered Robotic Overlords.
