I /thought/ we had solved the 32-bit OS on a 64-bit platform with
VOLK, but it is a particularly nasty issue. I know our 32-bit VMs on
64-bit systems works fine now. But this problem is difficult because
it's a fairly rare setup these days. Most things are now 64-bit
compatible, so unless you have a /very/ specific reason for using a
32-bit OS, my recommendation is to update to 64-bit. It'd still be
nice to not have this problem, but I just don't see the benefit of a
32-bit OS these days.
