Flash Crash on Ubuntu 64-Bit

[kalsig]

I'm running Ubuntu 9.04 64-bit with Opera 10.00 as my primary browser.
I've installed Flash Player v.10.0.32.18 for 64 bit Linux and I'm having trouble with the plugin crashing.
When it crashes in Firefox, the entire browser will go down with it, Opera will simply leave a blank space where the plugin used to be.
Stranger still is the fact that the plugin doesn't crash consistently, it might work fine for one Youtube video, but will crash consistently for another one.
I've already tried uninstalling all remnants of flash player and reinstalling the plugin again, still no luck. Is there a possibility that an old version of Flash is still lurking somewhere on my system? Any help or suggestions would be greatly appreciated.

I have this problem at work. It seems to be a bug in the flash library. I have not found a workaround that works for me, but there is one for AMD users.

You can try this, it make work for you.
Gentoo Bug 268336 - www-plugins/adobe-flash-10.0.22.87 crashes www-client/mozilla-firefox with "Illegal instruction"

It is a C application that you must compile. At the top of the C file it tells you what you need to do.

First of all, thank you for the reply, it was greatly appreciated.
It seems to have worked for Firefox, Flash appears to work correctly in Firefox, but I'm still getting the same issue in Opera.
Generally speaking, Opera has been able to see and use plugins in the ../firefox/plugins/ folder but it appears that Opera cannot load the "flashplugin-lahf-fix.so" plugin.
Is there a way to make this fix work for Opera as well?

Once again, thank you for your very helpful and quick reply.

Okay, so apparently Opera includes built in emulation for 32 bit plugins.
Here's what I've learned for the benefit of anybody else with this problem:
* Opera users can download the latest 32-bit plugin and place it in their ../opera/plugins directory - it will work without a hitch
* Older 64-bit CPUs will not be able to use the 64-bit flash plugin because they do not support the LAHF instruction
* coopstah13 instructions above will allow 64-bit flash to run on Firefox

You can try forcing it to load, I don't know how you start opera, but if you run from command line, try this instead

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/firefox/plugins opera

If you start opera from the menu, you can edit the shortcut file that starts it, put that before it.

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/firefox/plugins

Replace that /path/to/firefox/plugins with the actual path, i'm not on ubuntu so I can't tell you what it is, but you seem to know since you've put the fix in there.

Thanks for the assistance coopstah13, it was really appreciated. I think Opera is already querying the Firefox plugins folder, but the LAHF fix was not designed to work with Opera.
It appears that an Opera plugin emulator (known as Libmotif or something) has been built into Opera for several versions now. I think I can simply drop 32-bit plugins into the Opera plugins folder and Motif will take care of the rest for me. I just took the 32-bit flash 10 plugin and put it in the Opera plugins folder and it seems to have corrected the issue.
Thanks again for taking the time to help me out.
