I have a bit of a problem with my NetBSD configuration and I have seen other
posts mention the same error message "extra interupts" . Can anyone explain
what causes this error message to appear on boot up or how to correct it ?
Any assistance you could give me would be appreciated.

I have two disk controllers and adaptec 1542c scsi and an Ultrastore 12f (ESDI).
I boot NetBSD 0.9 off the scsi (whole disk dedicated to netbsd). I have a 330 
meg ESDI drive on on the Ultrastore controller. I have it partitioned into 
two partitions an MSDOS and a NetBSD Filesystem. I am only using the first 1024
cylinders of the Ultrastore drive. I have a,b,c and d partitions which point to 
the netbsd partition. I am only using the a partition. I use the h partition
for MSDOS.  I can access both partitions (mount and ls for example
work ok). My problem is I get an Extra Interupts error on boot up. I have also
seen the error when I go to write to the NetBSD Partition on the ESDI drive. I
usually crash the machine when I have a program generate output to go to the
ESDI drive to test it for instance. My IRQ's are set as in the INSTALL_NOTES in
the NetBSD Distribution. I believe the disk partitioning is good since I have
successfully newfsed my NetBSD partion and fsck it and everything seems fine. 
I ran my machine with just the scsi drive for a month with no wd device in the
kernal and I never had a problem or saw the Extra Interupts message. The
problem started when I compiled the Wd0 device in the kernal. I was just using
the ESDI drive for MSDOS up to that point. 

My friend has a 386 and a 486 also, with either dual or single IDE drives on
each. We tried both configs and he also gets an Extra interupts message when
booting.

Any Ideas, recommendations or solutions?
