Eric, I believe your mirror is lagging behind ab it?
I just installed 4.15.0-24-generic from -proposed and it fixes the issue for me
(tested 2 suspend cycles – previously it would fail 100% of the time).

This kernel (3.19.7), as well as the SRU-proposed 3.19.8, is also
affected by the ext+raid0+trim "chunksize not a power of 2

want this patch to land on my trusty system with -lts-vivid kernel. :)

I think the goldfish kernel is not maintained in the android source
package, but in this separate linux-goldfish package, so it's time to
move this bug again.
** Package changed: android (Ubuntu) => linux-goldfish (Ubuntu)
** Summary changed:
- goldfish kernel panic after setsockopt(…IP_ADD_MEMB
There's actually a fix upstream, :
https://android.googlesource.com/kernel/goldfish/+/0836a0c191f580ed69254e0b287cdce58481e978
I hope there are plans to rebase to a recent goldfish kernel some time.

I have now verified that building the goldfish kernel from git with the
upstream commit cherry-picked, and then booting that kernel in the
emulator, solves my issue with libupnp.

Thanks Joseph! I'm seeing the same effect described by Martin.
Boot+lightdm+loading Unity 7 is not as fast as it used to be in 16.04.
I need to compare timings (4.8 patched vs 4.8 vs 4.4) tomorrow to make
sure, but I also feel like it's a little faster now with the patches
applied.

I now believe I'm seeing two different issues in 4.8 that are not in 4.4 and
slow down my boot, which is very confusing.
- #1: High number of kworkers (fixed in 4.8 using the two patches and bisected
by Doug Smythies already)
- #2: Unknown other issue. I've noticed that when compi

Another issue with the 6.2.0-25 kernel is in linux-modules-nvidia-525-generic:
Provides: nvidia-dkms-525 (= 525.116.04-0ubuntu0.23.04.1),

But nvidia-driver-525 Depends: nvidia-dkms-525 (>= 525.125.06)
So the "dkms replacement" version provided by the pre-built modules

I believe with dkms, you need a C compiler and related tools, so that
the nvidia kernel module can be built on your machine during kernel /
driver updates. So that probably means more packages have to be
installed. It might also be a bit more error-prone?
