"kernel parameter" How to choose?

Hya,

I am having difficulties to find right kernel parameter(s) for my Debian on Toshiba laptop. Detail is http://www.linuxquestions.org/questi...d.php?t=585156

Documentation/kernel-parameters.txt reads that some parameters (irqpoll, pci=routeirq, irqfixup, acpi_pm_good, biosirq....) are used as workaround for buggy or broken BIOSes.

However, there are too many of them. It is practically impossible to check all combinations.

Is there any way to know which one to use when?

I appreciate any suggestion.

Happy Penguins!

A kernel parameter would not be appropriate as a true, permanent solution to a problem like that. For example, noapic turns-off a major subsystem ... basically "so you can reboot the thing long enough to fix the problem."

The kernel-configuration is normally specified when you build the kernel. It's in a hidden-file .config (note the leading "." which hides the file...) in /usr/src/linux. If you are using packages, the package-build or autodetect software ought to handle that messy chore for you.

It's frustrating. Yes, it is.

Hya,

Thank you very much, however, I am not that stage yet.

If noapic work, I will rebuild kernel. At this moment, I have not figured out which one or ones to use.

To be honest, I do not know how to build kernel with features of pci=routeirq and several other things.

And many other config options, I have tried, but obviously not all possible combinations.

It has been a long long way and still long long to go.

Happy Penguins!
