How to determine IRQ w/ PPC045 (Virtex II Pro)?
When writing device drivers for a 2.6 linux kernel running on a PPC405, in a Virtex II Pro, how do I determine which IRQ to use in my call to request_irq? I imagine that the IRQ will be directly dependent on how my device's interrupt is connected to the interrupt controller I'm using, but I don't know how to figure out the IRQ number. Any help would be appreciated.
Regards,

IRQ attachments are provided as #defines in the xparameters.h file generated by Xilinx EDK.

Init dies with unhandled signal 4
I am trying to move my Pico E-12 port from 2.6.15 to the current 2.6
from Linus's git tree.
Most everything moved fine, but now "/init" dies with an unhandled signal 4 which I beleive is an invalid CPU instruction.
I do not have this with 2.6.15 and Linus's tree is obviously more bleeding edge.
I am just asking whether I should be trying to track down a problem with my code or if this might be a problem in the git tree.
