Re: [Xen-ia64-devel] Serial woes with kexec on an HP RX2620

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, Horms

After kexec, what kernel do you use?
Xen or linux kernel?

I think you don't call iosapic_register_intr(),
arguments of iosapic_register_intr() are wrong.
Can you check that efi.hcdp is passed to second kernel properly?

FYI
In the case of xen, HP machine call the following functions. 
efi_setup_pcdp_console()
    setup_serial_console()
        setup_pcdp_irq()
            pcdp_hp_irq_fixup()

And iosapic_register_intr() is called in start_kernel().

Best Regards,

Akio Takebe
