ACPI: S3 and PAE do not like each other for now, S3 disabled.

ACPI: S3 and PAE do not like each other for now, S3 disabled.

[Arkadiusz Miskiewicz]

Is this ,,ACPI: S3 and PAE do not like each other for now, S3 disabled.''
generic S3 and PAE issue or just Linux issue only?

The case is ,,NX (Execute Disable)'' needs PAE to work on x86 but having S3 
working at the same time would be nice.

This may be bit-rot.
The last time somebody tested this IIR  S3 worked
exactly the same in PAE as it did in conventional MMU mode.

Linux only. Hmm with recent enough kernel we needed to fix this for
different reason, so it might just work.

Remove check, test it, if it works submit a patch.

It didn't work for me unfortunately.

My laptop went into sleep, fan turned off but LCD turned all white. After 
closing and opeing LID, fan started again, LCD turned back to live but screen 
was corrupted, random characters in different places.

Unfortunately I never tested S3 on PAE-disabled kernel so it's possible that 
my problems are unrelated to PAE (I hope that's the case).

Without testing the non-PAE case, this result is inconclusive.

In either case, it would probably be a good idea to run the
latest ACPI patch if you're experimenting with S3.

Tested non-PAE case, it worked (with few USB related problems) but my laptop 
was able to resume and react to my commands (+ no screen corruptions).

Will test with them next time which will be probably tommorow.

[Li, Shaohua]

Hi,
I did test it in my desktop (disabling HT and removing the check), and
it worked. Is there any special reason that you disabled it before?

Thanks,

Its wordwrapped, but looks good. If it worked once, its probably safe
;-).

Today while playing with suspend/resume support in via-rhine I had a chance to 
try it few more times (on 2.6.8rc2 with PAE enabled, maxdata notebook, 512MB 
ram, athlon, kt133 based mainboard).

Resuming works properly only somethimes. Once I have system back into nice 
shape, once I see that it starts resuming (fans are starting, screen changes) 
and it hangs, screen is corrupted (some color characters flashing), sysrq 
doesn't work.

Can you confirm that it works reliably with PAE disabled?

S3 is doing something "interesting" with page tables (switching to 1:1
mapping etc), it probably needs some hand-checking to see that it is
not non-PAE-specific.

I've tested 2.6.8.1 kernel with ACPI patch 20040715
- with PAE enabled - unfortunately no change. System hangs after resume 
sometimes in a way I've already described.
