yes, suspend/resume is working. I did three cycles and measured the time for
suspend:
The first suspend took approx. 60 seconds, the second and third approx. 30
seconds.
I see, it looks like its an issue with the ATA subsystem that is stalling
the suspend process.

Since it is a regression what you could do is use git bisect to try and locate
the commit that introduced the issue. But its time consuming and it doesn't
always work.
Other than that I think you should post a bug in the kernel bugzilla.
Best regards,
Emil

Then run the following and post the dmesg output after resuming. echo 1 /sys/power/pm_trace echo mem /sys/power/state Also did you try to suspend after blacklisting the wifi modules? I can take a look at it but note that it may require more skilled upstream people to resolve this issue.

I run now with nouveau and also purge the virtualbox stuff. Unfortunately, the behavior is exactly the same though (except that there is no blinking cursor with nouveau, when the system hangs), i.e. the resume works when I use freezer in debug mode, the system hangs when I go to the next level (devices). When you get a black screen does the system hang completely or is it possible to login to the system over ssh? If it's possible to login it could be useful to post the dmesg output here.

Bug#746602: skb_copy_ubufs() not exported by the Debian Linux kernel 3.2.57-3
Hello Jarno,
Yes it seems that the following commit should be included in 3.2.
commit dcc0fb782b3a6e2abfeaaeb45dd88ed09596be0f
Author: Michael S. Tsirkin m...@redhat.com
Date: Fri Jul 20 09:23:20 2012 +
skbuff: export skb_copy_ubufs
It applies cleanly on top of 3.2.58. However, the skb_orphan_frags inline
function
is not in include/linux/skbuff.h of kernel 3.2.58, but it is available in the
debian linux-headers-3.2.0-4-amd64 package. It seems like the following commit
has been backported to the debian 3.2 kernel but not to mainline 3.2.x.
commit a353e0ce0fd42d8859260666d1e9b10f2abd4698
Author: Michael S. Tsirkin m...@redhat.com
Date: Fri Jul 20 09:23:07 2012 +
skbuff: add an api to orphan frags
Probably these need to be included together.
Best regards,
Emil Goode

Package: linux-source-3.2
Version: 3.2.57-3
The symbol skb_copy_ubufs() is not exported in net/core/skbuff.c, even though
it is exposed in include/linux/skbuff.h and used by skb_orphan_frags(). OVS
kernel module fails to start due to this:
Error: Module openvswitch is not currently loaded
ERROR: could not insert 'openvswitch': Unknown symbol in module, or unknown
parameter (see dmesg)
dmesg output:
[ 3315.819202] openvswitch: Unknown symbol skb_copy_ubufs (err 0)
/lib/modules/3.2.0-4-amd64/source/include/linux/skbuff.h has this:
static inline int skb_orphan_frags(struct sk_buff *skb, gfp_t gfp_mask)
{
if (likely(!(skb_shinfo(skb)-tx_flags SKBTX_DEV_ZEROCOPY)))
return 0;
return skb_copy_ubufs(skb, gfp_mask);
}
But /usr/src/linux-source-3.2/net/core/skbuff.c only has this:
int skb_copy_ubufs(struct sk_buff *skb, gfp_t gfp_mask)
{
int i;
[snipped]
return 0;
}
Note the missing EXPORT_SYMBOL() after the function definition.
It seems that skb_copy_ubufs() has been exported in Linux 3.6, as the
skb_orphan_frags() was introduced. Now Debian 3.2.57-3 has a backported
skb_orphan_frags(), but the export of the symbol sib_copy_ubufs() was not
backported.

Jarno Rajahalme

Bug#721871: i915: add quirk to invert backlight brightness
Hello,
I got a black screen with wheezy 3.2.55 kernel on a HP G62 Notebook,
but the issue is resolved in kernel 3.12.9.
Could you test the attached patch with kernel 3.2.55 that adds the
invert brightness quirk?
It seems that adding the quirk is the way to deal with this issue
with older kernel versions.
Best regards,
Emil Goode
