current git breaks resume

current git breaks resume

[Jens Axboe]

Hi,

Unfortunately I'm a little short on time as I'll be travelling tomorrow,
but of course preparing a new kernel for the laptop is something you
want to do right before leaving. So I discovered that the current (well
as of yesterday, HEAD is 5986a2ec35836a878350c54af4bd91b1de6abc59)
doesn't resume on my x60. 2.6.20 works fine, so something broke since
then.

I think the patch from

http://marc.theaimsgroup.com/?l=linux-acpi&m=117103448629685&w=2

is likely to help.

Doesn't work, still hangs in the same way.

Well, looked promising ...

Still, I suspect the ACPI changes cause the problem to happen.

I've tested 2.6.20-git4 and it works on  my box (HPC nx6325, x86_64).
Unfortunately I have no i386 setup anywhere close to me right now.

Rafael

When I'm on stable ground again, I'll try with pm tracing and see if
that yields anything. Otherwise I'll do a bisect.

resume from RAM, or resume from disk?

Len,
resume from RAM is still broken by "Disable all wakeup GPEs". My 
previous patch for T43 does not help, only attached one helps (revert 
original patch).

[-- Attachment #2: fix-disable_all_wake_gpes.patch --]
[-- Type: text/plain, Size: 1049 bytes --]

Disable wake GPEs only once.

Resume from RAM, I never use suspend-to-disk.

With that patch applied, current git works as expected. Thanks!
