#6005 closed bug (fixed)

Freeze with local APIC

Reported by: tbe Owned by: mmlr
Priority: normal Milestone: R1
Component: System/Kernel Version: R1/Development

Blocked By: Blocking:
Platform: All


Haiku R1A2 freezes while loading the desktop unless I disable LOCAL APIC in the boot menu.

I have tried disabling APM/ACPI and leave APIC enabled, but this does not help.

What are the consequences of disabling LOCAL APIC, and is there a file somewhere to configure this permanently, or do I have to enter the boot menu every time?

Workaround patch until this bug is fixed. After applying one can run jam haiku_loader and replace existing haiku_loader with compiled one.

Could this be fixed by the latest changes to ioapic by mmlr?

comment:4 by tbe, 11 years ago

The freeze still happens in both hrev41490 and hrev41505 nightlies. The latter should be just after the changes diver refers to.

comment:5 by anevilyak, 11 years ago

The changes diver's referring to don't actually make a difference unless one explicitly enables them currently. Please try going into the boot loader and picking "Enable IO-APIC" in the safe mode settings (leave all other settings alone).

Thanks for mentioning that, anevilyak. Enabling IO-APIC takes care of the freeze, and also seems to improve responsiveness compared to disabling local APIC. With disabled local APIC, the system would once in a while take a 10-20 seconds pause.

Cool, then this one can be closed once the IO-APIC code has been enabled by default. For now you can force that setting by adding the line:

enable_ioapic true

To your kernel settings file.

Enabled by default in hrev41527.
