New Revision: 42795
Changeset: https://dev.haiku-os.org/changeset/42795
Ticket: https://dev.haiku-os.org/ticket/7971
Modified:
haiku/trunk/src/system/kernel/arch/x86/irq_routing_table.cpp
Log:
Relax ensure_all_functions_matched() to assume no interrupt use when a device
has no routing information but wasn't configured by the BIOS either. The
function will now only panic if a device that was previously configured would
not be so anymore after enabling the IO-APIC. Fixes #7971.
