... The problem in both is that I am unable to load apps locally from the GUI menu. ...Confirmed. I'll try to take a look tomorrow to see if I can spot the problem.
Although I found some 16MB RAM sticks to try and upgrade my 486 desktop PC to 36MB RAM, it looks like the 486 reboot problem is definitely in the kernel code anyway. I finally dug up this patch (https://lore.kernel.org/lkml/CANpbe9Wm3z8fy9HbgS8cuhoj0TREYEEkBipDuhgkWFvqX0UoVQ@mail.gmail.com/) in the kernel mailing list from Oct. 2024. The author says the first bug fixed by it "causes immediate reboot" on CPUs without CPUID support (486s).
Looking though the Git log for the patched file in the kernel sources (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/arch/x86/kernel/head32.c) it doesn't seem to have been merged, though it's not clear why. I guess then that all current unpatched kernels since v6.7-rc1 fail on 486 CPUs (the TC15 kernel was v6.6.8).
I'd ask about adding that patch to the TC16 kernel, but since it's released now I guess I'm a few hours too late...

Hi Uncle WarthogThanks! Let me know if there's anything you want me to test on my systems.... The problem in both is that I am unable to load apps locally from the GUI menu. ...Confirmed. I'll try to take a look tomorrow to see if I can spot the problem.
If you start apps from a terminal window do you see any error messages?
Before we think about recompiling the kernel, you might want to ask the kernel people why the patch wasn't included?
... Something to do with apps and 64-bit?No, something to do with apps and a "comparing ints of different signedness"
if ( sloc == string::npos ) {if ( (unsigned)sloc == string::npos ) {if ( (long unsigned)sloc == string::npos ) {Before we think about recompiling the kernel, you might want to ask the kernel people why the patch wasn't included?OK, I'll ask there on the weekend.

Is there much value in rebuilding TC for this, with the whole 16mb issue? Or are these devices stuck with custom kernels from here?
I see that the kernel developers are speaking of dropping support for i486 and early i586.
