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:

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

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