Either way, I couldn’t get the Debian 10 ISO version to boot in Hatari. 
Obviously it was too big for the real Falcon.

Thanks, Eero, but kernel debugging via Hatari is a bit beyond me a the moment.

Thanks Stefan,

That’s interesting and does suggest perhaps it’s a processor issue. Obviously I 
can’t address that sort of memory, but even adding AltRAM to Hatari when 
otherwise set to maximum Falcon compatibility hangs in the same way.

I’ve put together a video showing my experiments with Debian 10 too:-

I think changing my partition scheme and having a go with Debian 9 are next on 
my list.

(BTW, not shown on my videos was my other line of enquiry: putting Debian 
Potato on as well — that installed, but would frequently BUSERR out, often when 
just doing simple things [like ls -l]. Same on Hatari. Perplexing.)


Regards,

David.
