boot.msg for 2.6.38-rc3
[openSuSE kernel-pae 2.6.38-rc3.3.1]
[openSuSE pm-utils 1.4.1-1.2]
Starting with the 2.6.38 series, suspend to RAM completely fails. It simply reboots.
This is a Dell Inspiron 6400 laptop. Attached is my boot.msg.
Please tell me what further information you need for investigation.
The boot log does not show any sign of APM. A laptop this new would not use APM (it is an old legacy system) and is probably using ACPI.
Does 2.6.37 work correctly?
To Stephen: Ah, yes, sorry for mixing it up.
To Rafael: Yes, with 2.6.37 suspend to RAM works just fine.
Is the kernel 32-bit or 64-bit?
In that case I think it's caused by commit 5bd5a45 (x86: Add NX protection for
kernel data). It would be good to verify that, though.
Perhaps some kernel `command line option' could be temporarily added to switch this feature on or off... Then I can test this easily as soon as it gets added to openSuSE's kernel repository.
Unfortunately, that's just a kernel configuration option. I could prepare a
test kernel for you, but I think it's better to wait until this (known) issue
I'll let you know when that happens.
Ah, it's a known problem. I wasn't aware of this since I haven't found a bug report in bugzilla. Thanks for your help.
It's bug #27472 . However, I'm still not sure you're seeing the same issue.
At this point it's better to wait until the fix for that bug is merged and
test a kernel containing it.
Using 2.6.38-rc4-6-pae, it works again. Thanks for assistance.
