Hi Artur and Steven,
Perhaps we can raise this question to the kernel mailing list, it doesn't seem
there are people looking at this bug page. So can you please send an email to

Hi,
All 32 bit kernel I've tested resume ok.
All 64 bit kernel fail.
I haven't notice this in the beginning of this thread. Initially I think the
problem was related to kernel 3.2, but tha

Thanks Steven. So this means there is no known working 64 bit kernel.

Thanks for your test.
So this only occurs on 64 bit kernels, right?
The following kernel versions I mentioned are all about 64 bits, let's forget
32 bits kernels now, since they don't ha

I just tested Linux 3.9.0-rc2-00188-g6c23cbb on my Toshiba Portege Z830. It
still fails to resume from suspend without that extra udelay thrown in.

I haven't used my Toshiba machine for ages solely because of this bug, but I'll
re-image it and see how it behaves on the latest.

Hi Aaron,
maybe I don't explain properly. With all x86 32bit kernel I was able to resume.
The problem is with amd64. All kernel I tried (3.2, 3.3, 3.4 and 3.7) have the
same problem, fail t

Just tested locally with the above patch. The udelay() makes resume take
~1630ms, but it -does- successfully resume. Anyone have any ideas why the delay
is needed?

Looking at the code path for s3_beep, I am guessing that the actual code in
s3_beep isn't directly affecting suspend/resume. The code doesn't really do
anything too different from th

Fascinating. I just tested on the Portege Z830 with Linux 3.6.9, and I can
confirm that acpi_sleep=s3_beep somehow makes things resume just fine.

Hi,
Today I decided that I needed to debug this, because I need the 64-bit kernel.
I tried acpi_sleep=s3_beep to see if that can give me some clue, and...

No, the display never turns on.
There are no output with "no_console_suspend". Tried with normal boot and with
