I do not.
I can say I have experienced another similar problem described here where it locks-up on system-initiated restarts. Another "soft" restart gets it back.
My A500 is a native NTSC model, not that that should matter. It has a PAL/NTSC switch but since I am using an RGB to S-Video adapter at the moment, I will have to keep it in NTSC mode.
I have also experimented with removing the trapdoor expansion. It had no impact on the available fast ram.
