Hi
I do not know any detail, but I understand the issues, which have been reported before here.
I can just tell you that I have been running 6.0a on SDL Hercules/Hyperion 4.5 on a W11 machine with no apparent problems, at least in a short time frame (between IPL and shutdown).? I have no experience on Linux.
I guess the best thing to do is to post this issue on the Hercules forum and see what the people there (mostly Fish) say.? If I remember correctly a rather obscure bug was discovered and fixed in 4.5 a couple of months ago.
All the best
Marco
