pci=noacpi
Disable PCI IRQ routing of the new ACPI system.
pnpacpi=off
This option is for serial or parallel problems when your BIOS setup contains wrong
interrupts or ports.
notsc
Disable the time stamp counter. This option can be used to work around timing
problems on your systems. It is a recent feature, if you see regressions on your
machine, especially time related or even total hangs, this option is worth a try.
nohz=off
Disable the nohz feature. If your machine hangs, this option may help. Otherwise
it is of no use.
Once you have determined the right parameter combination, YaST automatically
writes them to the boot loader conguration to make sure that the system boots
properly next time.
If unexplainable errors occur when the kernel is loaded or during the installation,
select Memory Test in the boot menu to check the memory. If Memory Test returns
an error, it is usually a hardware error.
