Fifty percent? How do you derive that number?
If truly 50% of all VLB systems have that problem, then when VLB was prevalent FreeBSD would never have attained widespread use without disabling interrupts during IDE disk I/O as LInux does. But FreeBSD did attain widespread use and they did not disable interrupts.
It all sounds like fearful Linux mythology to me.
