[parisc-linux] zalon/ncr53c720 crashes K460 (parisc port) on bootup.

[Ryan Bradetich]

Hello all,

The zalon/ncr53c720 combination is fatal during booting on my K460
parisc box.  I believe the scsi termination is correct since I performed
a fresh debian install on the scsi disks and I can boot from then every
time I use a 2.4 kernel :)  This problem appeared with with the latest
cvs kernel from parisc-linux.org.

This system does boot and function when I do not compile zalon support
into the kernel and use a nfsroot.

I can provide addtional information and test patches (or give access to
this system) if requested.

Any thoughts or feedback appreciated!  

Thanks,

- Ryan

P.S. please copy me on any replies as i am not subscribed to the

Here is the relevant (I hope) information I copied from the bootup
