Kernel configuration 2.6.36-rc4

My Debian Sid (on a 2.6.36-rc4 kernel) reboots itself after opening my laptop's lid, that is coming from the suspend-to-RAM.

My computer is a Sony Vaio SR11M with an HD4500 Intel graphics card. Suspend and hibernate have always worked perfectly. However, with 2.6.36-rc4, although suspend to RAM works, coming from suspend (on resume) the laptop is reseted and it reboots.

Please find enclosed a copy of my .config


Kind regards,

Just in case you need extra information, I have a Core 2 Duo with 4GB RAM. Here is the graphics stack I'm currently using:


Mesa 7.8.2
Intel-gfx (driver) 2.12.0
Xorg 7.5
Xorg-core 1.7.7
libdrm2 2.4.21


Kind regards,

By the way, this happens with 2.6.35.4 as well. I just tried and there is the same situation.

Kind regards,

Well, so what's the last known good kernel?
Comment 4 Claudio M. Camacho 2010-09-16 04:49:13 UTC 
The last good kernel for my hardware is 2.6.34.7 (or any in the series 2.6.34.x). With 2.6.35 this issue happens.

Kind regards,

Please try to boot with acpi_sleep=nonvs in the kernel command line and let me
know if that helps.
Comment 6 Claudio M. Camacho 2010-09-17 05:56:14 UTC 
Hi,

"acpi_sleep=nonvs" works. If I use that option, suspend and resume work properly and the system does not reboot.
Comment 7 Rafael J. Wysocki 2010-09-17 21:23:16 UTC 
OK, please post the output of dmidecode from your machine.
Comment 8 Matthew Garrett 2010-09-17 21:26:10 UTC 
Also, could you provide the output of acpidump?

Hello,

I uploaded acpidump and dmidecode. Yesterday bugzilla was not working, so I couldn't do it earlier, I hope they help!

Kind regards,

Please check if your machine resumes correctly with this patch applied.

This in fact is a duplicate of bug 16396, so I'm marking it as resolved, but please test the patch from comment #12 nevertheless.

Hi,

The patch works for my SR11M :)

Comment 15 Rafael J. Wysocki 2010-09-20 19:50:06 UTC 
OK, so I assume the analogous patch in bug 16396 will work for you as well.

I'm closing this bug now, the patch from bug 16396 is going to go into 2.6.37.
