I have quite the same issue on my laptop. It's a Toshiba A100-193 (quite hard to find, it only existed during 2 weeks) with all the ATI chips like above. I tried with : 2.6.15, 2.6.17 (provided by Ubuntu), my own 2.6.17 and my own 2.6.18 (vanilla for both).
I also did a fixed DSDT for my laptop (there was one ACPI suspend to ram related error in it) and make it loaded by the kernel but I still have the bug. Bug : -I make it to sleep -It went to sleep correctly, I have the orange led that means it's suspended -I try to wake it up -I hear my DVD drive starting, but that's all, nothing else start and I have to remove my battery to be able to restart it. I also tried with a minimal kernel (no usb, no ethernet, no video driver, ...) but I'm still not able to suspend. Of course all the tests were done without any proprietary driver loaded. I attach : lspci, dmesg, dsdt.hex Ask if you want anything else. -- Toshiba Satellite M70-CL3 doesn't resume from suspend to RAM https://launchpad.net/bugs/64927 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
