Linux a problémy s ACPI / APIC

Dávám k dobru příspěveček, s jehož pomocí odladíte zamrzající bootování Linuxu:
Jak předat parametry zavaděči záleží na konfiguraci a druhu použitého zavaděče. Většinou pomůže F6 nebo Esc pro vstup do textového režimu, pak název obrazu k bootování a konečně parametr

např.
linux acpi=off

překlad následujícího textu dodám později. Princip ladění spočívá v postupném zapínání acpi-funkcí tak, abyste docílili největší funkcionality

If “acpi=off” allows the system to boot, try to isolate the ACPI issue with the following boot parameters in order to save the most features your ACPI can grant you (disabling it completely should be avoided since it plays an important role on powersaving and suspend management on nowadays laptops).

* Try booting with acpi=ht
This disables all of ACPI except just enough to enable Hyper Threading. If acpi=off works and acpi=ht fails, then the issue is in the ACPI table parsing code itself, or perhaps the SMP code.
* Try booting with pci=noacpi
This disables ACPI for IRQ routing and PCI scanning.
* Try booting with acpi=noirq
This disables ACPI for IRQ routing.
* Try booting with pnpacpi=off
This disables the ACPI component of the aLinux Plug and Play code.
* Try booting with noapic
Disables the IO-APIC for IRQ routing or PCI scanning.
* Try booting with nolapi
Disables the local APIC

NOTE: Only adding ‘noapic’ to the boot parameters has been reported to disable the USB ports. Only adding ‘nolapic’ has been reported to prevent the NVIDIA driver from loading correctly. However use of both ‘noapic and ‘nolapic’ is not know to cause these problems. Also if you use “IRQPOLL” or “IRQFIXUP” along with “noapic” will enable usb support. Feedback on this would be appreciated.
