With James's tree as-of today, on an ia64 tiger box, defconfig.
Unfortunately both add2line and gdb insist that 0xa0000001005419f1 points
at the start of mpt_interrupt, which is clearly wrong, so I have no simple
way of working out which source line is getting the null deref.
I tried with and without CONFIG_FUSION_FC. The driver is statically linked.
I guess I'll test this on x86 next. Is a bit of a bummer.

Just got into the office. Working on reproducing.
I'll keep you updated.

Ok - The problem is the module_init entry point for
mptbase.ko is not being called when the driver is statically
compiled into the kernel. Maybe when I moved registering
the pci ids to the scsi llds(e.g. mptspi and mptfc) that
mptbase.ko doesn't have its module_init called. The panic
in mpt_interrupt occurs when the ISR is calling the callback
handlers when cb_idx is 0xFF, and MptCallbacks is pointing to NULL.
The cb_idx would of been initialized to something less than 0xFF had
the module_init entry point been called.
I guess I will have to have the scsi lld drivers registering the pci ids
call mptbase.c module_init function, and maintain a flag so
its not called more that once.

That doesn't sound right. The kernel will call that module_init() function
for statically linked things.
This came out:
"Fusion MPT SPI Host driver 3.03.00"
So fusion_init() is being called. Maybe the problem is that fusion_init()
is being called at the wrong time.
That doesn't sound right either. This:
"SCSI subsystem initialized"
is coming out earlier on, as one would expect with a subsys_initcall().
Ho-hum. You'll work it out ;)

You can shuffle the ordering of these things with late_initcall(), etc.

Look at the dsc02504.jpg you sent earlier today. Only mptspi_init was
called. Not fusion_init.
When fusion_init() called, it would display
"Fusion MPT base driver 3.03.00".
The message "Fusion MPT SPI Host driver 3.03.00" came from mptspi_init.
Anyways, I have it solved. A patch soon follows.
