Kernel configuration 2.6.36-rc4
PM / ACPI: Blacklist system known to require acpi_sleep=nonvs
Description Claudio M. Camacho 2010-09-15 10:24:12 UTC
Created attachment 30112 [details] 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, --Claudio

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, --Claudio

By the way, this happens with 18.104.22.168 as well. I just tried and there is the same situation. Kind regards, --Claudio

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 22.214.171.124 (or any in the series 2.6.34.x). With 2.6.35 this issue happens. Kind regards, --Claudio

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.

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, --Claudio

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 ***
