Hi, having problems here with the current (supped latest at about
12:00AM Sun, Mar 12) kernel sources. This problem also goes back a
week or two, because I have tried several other kernels, one built as
far back as 2/25, one which should be compatible, except for several
peripheral addresses. The problem comes when the kernel probes the
ncr0 device at startup. As you can see, it panics:
ncr0 <ncr 53c810 scsi> int a irq 12 on pci0:17
reg20: virtual = 0xf2dc4000 physical = 0xffbdff00
CACHE TEST FAILED: reg dstat=sstat2 readback ffffffff.
CACHE INCORRECTLY CONFIGURED

hit reset please
This is for a P90 running on a (its crap damnit!! I'm getting a new
one soon) OPTi based VL/Super Motherboard, with the NCR card on pci
int a, mapped to isa irq 12, as you can see.
I notice that the addresses listed for the ncr device are different in
the good boot. Oh, another note, these kernels that are failing were
all built on different machines, that shouldn't matter should it?
This particular one was built by swallace@freebsd.org.
This is a normal boot on a kernel built from the 2/10 SNAP sources, I
would be very content with this kernel except I forgot to compile in
ptys so now I'm kind of stuck. Is this a hardware problem, or what?
I can't really figure it out.
