Hmmm - I didnt have a look at that - I was assuming that alloc_bootmem returned a physical address. In 2.5 it seems we dont write out the allocated address on boot as we did in 2.4 (hint, hint) > I would also check that the suspend/resume doesn't choke somewhere in > 32-bit land by jumping over the call to acpi_enter_sleep_state in > wakeup.S. I kind of had to debug this on this machine - No legacy hardware nice for debugging (Parallel, Serial etc). Even the speaker is switched through the sound card so when the chip is still powered down - no sound.
