Yeah, I do have APIC enabled. I'm using the local APIC and the IO-apic. 
My Celeron PPGA 500 does have an apic. Could the apic be causing the
interrupt timing problems?  Sorry about the double post.

I just solved my lost interrupt problems. I just moved my Caviar hard
drive from secondary master to primary slave. and I've not received any
lost interupt errors. But I may just recompile my kernel without apic. I
also have an SMP-capable controller that is also used for the sensor. But,
I know I don't need an apic for the sensor to run.

(I wonder if the apic is throwing off my LM80's readings. That's a
different matter.)

hdc: lost interrupt

[Derek J Witt]

[-- Attachment #1: Type: text/plain, Size: 5261 bytes --]

Good evening, all. I've been trying to get 2.5.x to boot up without
losing IDE interrupts.  I tried disabling multimode in makeconfig but to
no avail.

My IDE controller and chipset are as follows (via dmesg):

ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later

hdc: 12594960 sectors (6449 MB) w/256KiB Cache, CHS=13328/15/63,

And /proc/pci reports my chipset as such: 

  Bus  0, device   0, function  0:
    Host bridge: VIA Technologies, Inc. VT82C693A/694x [Apollo PRO133x] (rev 196).

      Master Capable.  Latency=32.  
      I/O at 0xe000 [0xe00f].

Has anyone else with a Via chipset been able to boot into 2.5.x without having these interrupt problems? Any suggestions will be helpful.

Thanks.
