ide-scsi and SMP does not work together.

ide-scsi and SMP does not work together.

[Klaus Umbach]

Hello Support Center :-)

Since I have 2 CPUs on my mainboard and compiled the SMP-support in, I
cannot use ide-scsi anymore. I guess it must have something to do with
apic, because when I use "Local APIC support on uniprocessors", I have
the same problem. With no SMP and no local APIC everything works fine.
(except the second CPU, of course). Normal ide-cdrom support works, but
recording CDs over atapi is not really what I want at the moment.

SMP by default uses the I/O-APIC, and may (depending on kernel version
and .config) also use ACPI, which in turn may trigger ACPI-controlled
PCI IRQ routing.

Try "acpi=off", "pci=noacpi" (or however that don't-use-ACPI-for-PCI
option is spelled), and "noapic" (don't use I/O-APIC).

No, that didn't work. I got the same error-messages. :-(
