Apparently, the –

Exception "Line 1111 Emulator" ($2c) at $7A008 occurred'

is an FPU access - according to information from Jens Schoenfeld(!). Which I find curious, as the system has never had an FPU on it. He suggested to clean the system of FPU-requiring software (whatever that means) and to check datatypes.

Nevertheless, that is just one of the errors, and more frequent ones have been popping up when for example doing a memory check with Keir Fraser's SysTest (which only occurs when the ACA accelerator is plugged in). I'm thinking the errors from whdload are *not entirerly accurate* due to the system instabilities.

There was also a suggestion that this was PSU-related (which could potentially be the case), but apart from the two 4.5A A500 PSUs I've been using I don't have another third one to test with.

But it lends the question, have anyone here experienced system instabilities which were caused by a bad PSU? (and which only occurred when having an accelerator card fitted?)
