SCSI PMC card

[Brian Waite]

I am trying to put a Cyclone SCSI PMC (symbios 53c895 chipset) card on my
Motorola MVME2400 and I see some wierd stuff. If I put the SCSI card on a
SPAN card, the kernel comes up and see the card, but when I place the SCSI
card on either of the 2 PMC slots on the base, I hang while probing PCI
hardware. It gets part way through the PCI fixup resources section and just
hangs. Here is my boot
Linux/PPC load: console=ttyS0,9600 root=/dev/ram0
Uncompressing Linux...done.
Now booting the kernel

A thing to note is that I do not have and SCSI support built into this
kernel. I built scsi_mod, sd_md, and sym53c8xx and load them as modules.
I am using the 2.4.3 kernel and I have tried building the sym module into the
driver, but the hangs occurs before the driver ever loads! Any idea what has
gone wrong while tring to probe this card? It is strage that it works fine on
a SPAN card. Too bad that is not a solution for us. PS this worked under 2.2
so I know the card is OK.

Thanks

Any help would be great thanks.
