No, the machine should be fine in and by itself. Two computers ago, it was
my main workstation. I just changed it again to boot in 2.2.21 and copied
/usr/sbin/memtest (from the sysutils package) over; memtest is currently
running merrily and I'd be surprised if it showed something.
I suspect that I am falling victim to either a resource starvation (that
would be rather bad as 2.4.* ought to boot in 32mb) or, more likely, a
misconfiguration. The odd thing is that by now, the larger of the two
working 2.2.2* bzimages is 711k, whereas the non-functional 2.4.19 is 737k,
or only 26k more. That can't be it.
I must be missing one dreaded configuration. Darn.
Thanks again, Dirk
