[parisc-linux] Kernel panic on D270/1 when loading EISA driver

[parisc-linux]

Hi All,

I'm currently trying to convert an old HP 9000/861/D270 to a firewall. So far, 
It works fine (after lowering the NCR_700_MAX_TAGS in drivers/scsi/53c700.h 
to 4, without that change the SCSI bus hung when writing large amounts of 
data).

The only real problem I have right now is that I get a kernel panic when 
loading my 3c59x driver module, because "ASSERT(dev);" fails in function 
ccio_map_single in file arch/parisc/kernel/ccio-dma.c.

I haven't found anything on the list so far, so maybe this is a new problem.
(Are EISA devices treated as PCI devices? Otherwise it might be ok for dev
to be NULL...)

Versions:
    Linux hppa 2.4.20-pa33 #2 Wed May 7 19:41:42 CEST 2003 parisc
    gcc version 3.0.4
    GNU ld version 2.12.90.0.1 20020307 Debian/GNU Linux

config, System.map and dmesg.log are available from 
http://134.155.63.117/~skettler/parisc-linux/

Thanks in advance,

Sascha Kettler

Yes. But there needs to be a fake pci_dev so the ccio mapping services
can find it's IOMMU data structures. Either Ryan Bradetich or James
Bottomley might know off hand what the problem is for EISA. This
is not a new problem.
