Sorry, spoke too soon. The instability wasn't caused by SEGMAPSIZE. I
guess I applied the updates too hastily. :)
Apparently there is some incompatibility between my #9 Motion 771 VLB
card and the 9/pc/vgargb524.c hardware cursor stuff. After commenting
out the hwgc entry in vgadb the problem went away.
Symptoms included black screens of death when resizing windows and/or
moving the mouse, sending the monitor into a out-of-sync tailspin,
hanging the machine, and frying the local kfs file system.
The hung machine and tossed file system seem to be a fairly strange
effects for hwgc incompatibilities. I wonder if there isn't a bad
pointer in the code somewhere.
Any thoughts on this? Thanks.
Ciao,
Erik
