Yes, your ACPI-based system will not boot. > Would it do harm to the hardware? It might, try it and see :) good luck!!! greg k-h ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
Re: Where to place my driver

OK I did not expect that to be a thing, seems like that is what I need. > start with drivers/hwmon/ and if the developers there don't think that > it should be there, let them tell you where to put it :) I will be on holiday until end of next week, I will send in the first 3 patches for fan support when I'm back home. I will add temps and LED later on. Maybe I will also add fan/pump speed curve, maybe.

Are there some potentially serious problems that I should be aware of if I totally disable the CONFIG_ACPI option on the X86_64 platform?
Hi, list Are there some potentially serious problems that I should be aware of if I totally disable the CONFIG_ACPI option on the X86_64 platform? Would it do harm to the hardware?

Re: How do you investigate the cause of total hang? Is there some information that I should pay attention to in order to get some hint?

The kernel log tells what kind of crash it is, a NULL pointer deref, a kernel page fault etc.. If the hang was a hard lockup, you have to turn on lockup detector and also kdump to capture what the detector tells.
