Hi there! 

Could anyone help me with the following problem:

I have a Tyan TomCat III mobo running two 133Mhz Pentiums
Linux 2.0.29, SMP enabled, NCR 53c810 support is compiled into 
the kernel. 

I've got a PCI Fast-SCSI-2 hostadapter with the NCR 53c810 chip
*without* any scsi devices on the scsi-bus. It's in the first 
PCI slot, set to INTA, level enabled interrupts. 

The linux kernel recognizes the adapter and initializes it, but 
then it waits for a timeout and then resets it, then again and 
again (infinite loop)...

Is it possible that this is because that are no scsi devices 
attached to the bus? I also don't have any terminators to the 
external and internal connector attached. It's not an ASUS SC200
and as far as I know it's not one with active termination.. 

Here some of the boot up messages (not exactly though):

scsi host 0 abort (pid 0) timed out restarting
scsi bus is being reset for host 0, channel 0, 
nec53c810-0: restart (scsi bus restart)
scsi: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0, lun 0
	test unit ready 00 00 00 00 00 
nec53c810-0: abort_call

[infiniely repeated]


Mucho thanks in advance!

	I have an adapter with the same chip, made by Soyo. I don't
have the problem you are encountering. The controller I have doesn't
have a way to set termination on the board ( it has to be done on the
device that is last on the scsi chain ). On the controller there is a
Conner tape drive and a Zip insider. I am running Slackware kernel
2.0.29. One remedy for your problem ( since you don't have anything
plugged on it ) is to pull it out and put it back in when you buy some
scsi device ;-)
