RE: Button events lost after S3 on Thinkpad R32

[Li, Shaohua]

Hi,
I have tested S3 in many machines, and all tests show ACPI interrupt lost after S3. /proc/interrupts shows no ACPI interrupt increases; power button and any ACPI related button can't generate any events. I guess ACPI need be re-initialized after S3. Patch in bug 1409 can resolve S1 problem but not S3.

Thanks,
Shaohua

Just to let you know: my system is fine after S3, i.e. ACPI interrupts are
not lost (it's an ASUS L3C laptop, FYI).

Thanks , but it cannot solve SCI interrupt lost after resuming from S3.  --Luming

test11, with quite a lot of patches actually:
- http://bugme.osdl.org/attachment.cgi?id=1208&action=view
- http://bugme.osdl.org/attachment.cgi?id=1029&action=view
- http://bugme.osdl.org/attachment.cgi?id=1257&action=view
- Dmitry's input suspend / resume support patches
- possibly others, less relevant

Though as far as I remember, I never had problems with ACPI interrupts
after S3 resume, only after S1.

That patch doesn't intend for resolving S3 Button events lost issue.  Maybe you can file a tracker for it, and let's follow up there. --Luming

Yeah, no interrupts either.
I tried looking at bugzilla, but hadn't noticed that one.

Anyway, the patch doesn't work, as Shaohua observed.

Button events lost after S3 on Thinkpad R32

[Brian Perkins]

Hi all.
I understand that this problem also shows up in the R40

After doing echo 3 > /proc/acpi/sleep

and then resuming, events no longer arrive in /proc/acpi/event. 

I doesn't matter if it's tiggered by a lid event, or done by hand, the 
same thing happens (I thought there might be some kind of a race for a bit)

Everything else seems to work.  I can sleep by hand, and by lookng at 
the /proc/ entry I can see that the lid opens and closes.

Here's the DSDT
http://throb.netspace.org/~bperk/dsdt-IBMR32.dsl

There is a typo in this DSDT, but fixing it doesn't seem to help.

I tried to debug this a bit by setting debug_layer to 0x4 (for the event 
layer) and the level to 0xffffffff, but I couldn't really see anything 
too suspect.

How's the /proc/interrupts after that? Does it show any ACPI interrupts
occuring? Anyway, you moight want to check on this:
