Hi all,

any help is wellcome...

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
CS5530: ide CONTROLLER AT pci SLOT 0000:00:12.2
CS5530: chipset revision 0
CS5530: not 100% native mode: will probe irqs later

when I look in my /proc/interrupts I see something strange

NMI:         0

this is my machine configuration:
- GEODE GX1 BGA 200MHZ
- 64MB
- CS5530 with 2 controllers IDE master primary CompactFlash and master secondary, without slave connectors.
I tried all of present configurations from ide.txt and all that I found in the internet about this, and ever I get lots of <hda: lost interrupt>. 
The incredible is that hdc work fine, and I undertand why.

Yes I tried all
   - ide=nodma
   - hda=noprobe
   - set default values to ide0
   - ide0=serialize ide1=serialize
   - disabling acpi and apic
   - chage CompactFlash
   - checking

thank´s
