Does anyone know what is the status of flash9 or flash10 in RELENG_7 ?
Following the thread of a couple of months ago, i tried to:
- remove all linux-* ports
- set the following in /etc/make.conf
	OVERRIDE_LINUX_BASE_PORT=f8
	OVERRIDE_LINUX_NONBASE_PORTS=f8
- set the following in /etc/sysctl.conf
	compat.linux.osrelease=2.6.16
- set the following in /etc/fstab
	linproc /usr/compat/linux/proc  linprocfs       rw 0 0
- reinstall linux_base-f8-8_11
- reinstall linux-flashplugin-10.0r22 (which in turn brings in the
  relevant linux-f8-* ports)

- also install nspluginwrapper and create a firefox plugin
- upgrade firefox to firefox-3.5,1 (native), just in case
- run firefox with "limit stacksize 4megabytes" (or variants)
  as recommended to avoid npviewer growing/not dying

This was done on 3 different machines (one laptop with a centrino,
2 desktops with AMD X2 dual core running in i386 mode) with mixed
[in]success. On one machine thing started working well, but on the
other two they did not (the various packages were of course slightly
disaligned) and while trying to replicate the configuration i also
broke the good one without figuring out why.
Symptoms are that on certain sites or actions (e.g. switch to full
screen on youtube videos) i get firefox freezing like this

22381 luigi  13  96    0 82580K 57484K ucond   1   0:00  0.20% firefox-bin
22413 luigi   1  97    0 72920K 33448K futex   1   0:00  0.20% npviewer.bin
22414 luigi   1  97    0 72920K 33448K futex   1   0:00  0.20% npviewer.bin

and recovering control (but no video) after 10+seconds

I also get a lot of the following weak_unref warnings with various addresses

(firefox-bin:22381): GLib-GObject-WARNING **: IA__g_object_weak_unref: couldn't find weak ref 0x297ba9f0(0x2a10d110)

(but not sure how related is this, because it happens even without a
flash plugin).

I have also tried flash9 instead of flash10, o fc10 instead of fc8,
all with similar results.

Is there a recipe for a working flas9 or flash10 operation ?

cheers
luigi
