Hi all, You may remember a couple of earlier messages I sent on this list two weeks ago re: strange hangs, reboots, SIGBUS etc after upgrading to a PCI, AMD4/120 Hippo15 motherboard, Tseng ET4000/W32 video, Western Digital 1.6GB EIDE hard disk. Well, things have settled down now - this has been the upgrade from hell. Everything went wrong! One of my old hard-disks started playing up and acting flaky and has been removed, this was at least one of the problems. The new harddisk I purchased had problems (soft & hard errors reading) and has now been replaced. My old 30 pin SIMMs (via 30->72 pin converters) have been replaced with new 72 pin SIMMs. Finally the BIOS settings have been changed to run the PCI bus at 20 MHz instead of 40 Mhz. Now I have a system which runs FreeBSD reliably. I have tried to push the machine over (heavy compilation under X with lots of network traffic) and it seems to be running fine. BUT if I run DOS and use it to play games (why else?) I have seen some strange things. IndycarII runs pretty well but occasionaly it crashes with a 'Page Fault'. Upon rebooting to FreeBSD I usually get a hung system when the 'routed' daemon starts up, occasionally the system waits until 'Clearing /tmp' before hanging, and once or twice it has booted, started X and then crashed after about 30 seconds. The kernel panic in this case was a page fault. This is repeatable, a cold-start doesn't help either. The only thing that seems to help is to leave the machine powered down for several minutes before making a cold start. Any ideas? What kind of problem could live through a cold-start? Regards/mark
