System reboots itself on resume (coming from suspend)

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
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:
Intel-gfx (driver) 2.12.0
By the way, this happens with 126.96.36.199 as well. I just tried and there is the same situation.
Well, so what's the last known good kernel?
The last good kernel for my hardware is 188.8.131.52 (or any in the series 2.6.34.x). With 2.6.35 this issue happens.
Please try to boot with acpi_sleep=nonvs in the kernel command line and let me
know if that helps.
"acpi_sleep=nonvs" works. If I use that option, suspend and resume work properly and the system does not reboot.
OK, please post the output of dmidecode from your machine.
Also, could you provide the output of acpidump?

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

PM / ACPI: Blacklist system known to require acpi_sleep=nonvs
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.
*** This bug has been marked as a duplicate of bug 16396 ***
The patch works for my SR11M :)
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.
