fatal kernel trap

[Rob Dosogne]

I have been receiving the same crash & halt code on my 600au with the 
same QLogic SCSI card during installer boot.  I will have to try it in 
a 64-bit PCI slot.  I've been searching for the solution to this 
problem since late last year!

Does anyone know why we are getting a crash from SCSI in 32-bit?  It 
would be interesting to find out.

cheers,

Rob Dosogne, your friendly neighborhood sysadmin.
