Try changing the last argument of request_irq() in PMacIrqInit() and
free_irq() in PMacIrqCleanup(). For example, change
request_irq(awacs_irq, pmac_awacs_intr, 0, "AWACS", 0)
request_irq(awacs_irq, pmac_awacs_intr, 0, "AWACS", (void *)awacs)
free_irq(awacs_irq, (void *)awacs).
I think that's what I did in order to get rid of the panic.
For the wake up problem, does it help if you put the code similar to the
following in awacx_sleep_notify()?
oöout_le32(&awacs_txdma->control, (RUN|WAKE|FLUSH|PAUSE) << 16
out_le32(&awacs->control, (in_le32(&awacs->control) & ~0x1f00)
| ((awacs_revision < AWACS_BURGUNDY)? BEEP_SPEED:0) << 8);
out_le32(&awacs_txdma->control, RUN | (RUN << 16));
