This may be off topic, but I am having problem with my custom 8245 board.  We 
migrated an x86 design to a MPC8245 and kept the ALI M1535 Southbridge.  the 
problem is that the 8259 interrupt controllers output always seems to be masked 
after a warm reset, but everything works fine from a cold boot.

When poking at the 8259 registers, they show that interrupts are ready but the 
INTR pin is never asserted to the  8245s EPIC, hence no interrupt.

After a cold boot, it will run fine until it resets.  Once it resets, there are 
no interrutps reported by the INTR line to the EPIC (but internal EPIC 
interrupts like the internal DUART work fine).

Any ideas?

Thanks for indulging me on the OT message but I'm stumped..
