Description Fadi Adlouni 2004-11-28 14:40:07 UTC

Hi.
I'm running gentoo-dev-sources kernel. version 2.6.9-r6. i'm using swsusp.
suspend to disk works fine, however suspend to ram after i resume it, everything comes up, then couple of seconds later it drops to console where i see kernel oops! looks like it has to do with vesafb, here is the related info from /var/log/messages :

this happens after i resume.

i notice the following lines before it suspends:

Oct  2 23:17:14 fadlouni-laptop MCE: The hardware reports a non fatal, correctable incident occurred on CPU 0.
Oct  2 23:17:14 fadlouni-laptop Bank 1: f2000000000001f5

i've tried removing lots of modules before suspending just in case, but it doesn't matter.

this didn't happen on an older kernel ( 2.6.8x) but i think at that time i was using swsusp2, which as far as i understand has been removed from 2.6.9 .

this is my first bug i file so don't flame me if i missed something :-). I'm also not good about debugging kernel issues, so if more info is needed can you explain in detail how to do it?.

that's the only thing broken on my laptop now, please help!.

Thanks,
Fadi.

I recommend you to try devlopment sources 2.6.10-rc2:

ACCEPT_KEYWORDS=~x86 emerge -va development-sources

Comment 2 Fadi Adlouni 2004-11-28 16:36:34 UTC

thanks for the reply.
just tried it with no success.

at first with vesafb (doesn't have tng version), i only get a blank screen at boot up. so i disabled framebuffer and vesafb.
then after testing swsusp, when resuming i get:
Nov 29 01:20:49 fadlouni-laptop MCE: The hardware reports a non fatal, correctable incident occurred on CPU 0.
Nov 29 01:20:49 fadlouni-laptop Bank 1: f2000000000001f5
it continues a bit then hangs!.

i do prefer if we can make the gentoo-dev-sources work, as i do need framebuffer and it seems it's only working with vesafb-tng

Does suspend to ram work if you do not do sus-to-disk before? I *think*(I am not sure), I have heard similar reports on the swsuspend-devel list. Maybe this bug is a upstream bug, you should file it at http://bugme.osdl.org/ and close this as UPSTREAM.

Comment 4 Henrik Brix Andersen 2004-11-29 05:47:42 UTC

I see the same problem here with development-sources-2.6.9 - seems suspend-to-disk and suspend-to-ram clashes...

Comment 5 Fadi Adlouni 2004-11-29 05:50:20 UTC

when i'm testing i'm doing suspend to ram directly after bootup. so it's without doing suspend to disk.

should i still file a bug http://bugme.osdl.org/?

Thanks.
Fadi.

Yes, please file a bug there as this is a problem with the mainline kernel, not ours.
