Hello, I am running linux on a mpc5200 chip and Im having problems with the mpc5200's simple and wakeup interrupts. The version of Linux I am starting with is linuxppc_2_4_devel_1_0_0 from Denx. Modifications have been made to the kernel, but none for enabling the wakeup register set and/or the wakeup interrupts. Does a patch exist to enable this behavior? Can anyone point me in the right direction if I would like to enable the wakeup interrupts myself? I noticed the behavior when attempting to write a device driver to interface with the psc1_4 pin on the mpc5200 chip. I am able to get the chip to generate interrupts, but when the interrupts occur I get the following error message in /proc/kmsg "Unhandled interrupt c, disabled". After getting this error, I installed an interrupt handler on IRQ 12 (hex c). This caused the kernel to lock up. Thanks for any help, -Ron
