[PlanetCCRMA] can't boot any 2.6.12x kernel

[pirrone]

My Dell 470 Workstation with 2 Xeon processors and 2 SCSI drives running 
off a Perc 320 /DC hardware controller in Raid0, nVidia Quadro NVS and 
Audigy2 running a fully updated Fedora Core 3 throws a kernel panic with 
the Planet 2.6.12-0.21.rdt.rhfc3.ccrmasmp kernel, also 
2.6.12-1.1372_FC3smp and 2.6.12-1.1371_FC3smp. 

Everything works fine with uniprocessor 2.6.12-1.1372_FC3 and all other 
2.6.11x-smp kernels including 2.6.11-0.3.rdt.rhfc3.ccrmasmp from the Planet.

With acpi being a problem affecting earlier SMP kernels I tried adding 
acpi=off to GRUB which altered the particular panic behavior (all panics 
reported multiple Symbol not found messages) but still resulted in a 
panic boot abort. 

I'm searching for this problem and of course a solution but haven't 
found it yet.  Anyone here able to shed any light on this?  Again, all 
2.6.11x kernels both SMP and UP boot fine, only UP 2.6.12x will boot 
with all 2.6.12x SMP unable to boot at all.

Thanks for any help!
