Were I to speculate, I'd say it might be memory-related. Maybe your BIOS somehow uses some part of your memory on the 'upper end'. And only when your computer's run long enough so FreeBSD actually writes something there suspendig fails. You could try with a simple 'malloc all avail ram, and write to it sequentially' Then try to suspend every few MB of overwritten ram. You could then compile a kernel with an aprropriate MAXMEM="(128*1024)" option, and see if that fixes it. I'm speculating about this, because my old Compaq aero, upgraded to 20MB would crash if you'd access the MB between 15 and 16. Good Luck, CU, Sec -- I know that you believe that you understand what you think I said. But I am not sure you realize, that what you heared is not what i meant.
