Yep - I whipped up the following patch (have yet to diff it). Try it on
your system and let me know if it works.
In /usr/src/linux/arch/i386/kernel/io_apic.c
@ Line 1214
#define PIC_IRQS ((1<<2)|(1<<13))
change to
#define PIC_IRQS ((1<<2)|(1<<9)|(1<<13))

Ingo - I noticed the whitelist / blacklist stuff inside io_apic.c and
tried adding in a routine to the setup_IO_APIC routine to define the
io_apic_irqs but that does not seem to work. I went off the whitelist
section where io_apic_irqs = ~PIC_IRQS and tried to setup a different
variable ie: io_apic_irqs = ~DKPIC_IRQS where DKPIC_IRQS =
((1<<2)|(1<<9)|(1<<13)).
Is there a way to make the change depending upon the Product_ID ??
So there would be a:
if (Product_ID == "DK400LX")
io_apic_irqs = ~DKPIC_IRQS;
else
io_apic_irqs = ~PIC_IRQS;
Or is this impossible to do at runtime. I guess that at runtime is the
only way to determine which Product_ID we are running on.
Thanks!
