Thanks Michal;

I tried your fix above now and before that, I always removed
\noalign{\medskip} from file using global search and replace.

In both case, when I compile the file I get

Output written on KERNEL.dvi (487 pages, 3437956 bytes).
Make4ht: Fatal error. Command tex4ht returned exit code 256
[stderr] --- error --- Illegal storage address
Makefile:14: recipe for target 'KERNEL.htm' failed
make: *** [KERNEL.htm] Error 1

I have no had time to make a MWE yet. It is strange
that only when I remove \noalign{\medskip} this happens,
it must be triggering something else.

Have to run to class now but will try to see if I can make a MWE
for this. If not, I'll switch back to SVG to compile this file.

Thanks for the help.
