I'm having some problems with the IO-APIC on a Acer Aspire 1501LMI laptop (AMD64). When the IO-APIC is enabled it misses some interrupts. Using noapic makes everything work fine.
The problem appears during fifo transfers when interrupts are frequent. My guess is that if a new interrupt is signaled while still in the interrupt handler, the new interrupt gets ignored.
The device in question is a LPC/ISA device.
Are there perhaps some special commands that need to be executed by the driver when on an APIC system?
