Gerard,
The version 1.2 driver for the 53c896 seems to have problem dealing with
bus-mode changes and in particular, with single-ended devices. I am
getting a message...
ncr53c895-1: unknown interrupts(s) ignored, ISTAT-0x22 DSTAT=0x0
SIST=0x1000
with other messages, but it continually goes into a reset cycle and does
not give up. If I remove the single-ended device from the bus, the
driver returns to normal.
I have tried different combinations and it points to my single-ended
device. I have two controllers, they both work fine with the LVD
devices, but they both fail with the single-ended device (dds-3 tape
unit) attached.
Have you seen this problem?
<>< Lance.
