SubjectProblem with IDE harddrive and ATA FLASH on the same IDE channel
I am working on a board that has both an IDE drive and an ATA flash on 
the same IDE channel. If I use them independently, they work fine. If
I try to use them together (say, copy files from one to the other) I get
lost interrupts, spurrious interrupts, etc. Can you have a HDD and
FLASH on the same IDE channel? This is on a Serverworks OSB4, I've
tried various kernels. One wierd thing, if I compile the Redhat 7.2
kernel with Redhat's compile, it does seem to work. If I compile it
with a 2.95.3 compiler (on SuSE) it doesn't work. I've tried playing
with timing, with and without DMA, etc.

Any ideas on this or how to debug this?

Thanks,

-Corey

heres the kernel output on the error:
