I am running FreeBSD 2.0.5 installed from the cdrom. The attached drive is an 2.3 GB HP drive. The Pentium installed is a 90Mhz Pentium. After changing the motherboard and the SCSI controller from an adaptec 1542A to an PCI 4290 the system comes up very fastly as expected. (Some strange core-dumps occured in the following process). Trying to determine the better SCSI performance I was running bonnie. The system crashes with a panic giving something like: Page fault: supervisor write, page not present (This seems to be an already known bug-report with the number 688 in GNATS) After several tries my filesystem was so messed up (after several fsck's) that even the kernel wasn't found anymore. So I decided to reinstall. I was not able to reinstall sucsessfully. The system crashes at the time to make a newfs on the larger /usr-partition with the same panic. FYI, the things I tried to solve this problem are: - running the installation with an old Hercules card - I changed the PCI 2940 back to the 1542A - I tried nearly everything in the bios systematically - I disabled internal and external caches - I put down the system speed to 75 Mhz, all caching disabled, Then I was at my end. My conclusion is that is HAS to be the motherboard or chipset. Now I am running my old system again after reinstalling. I would be glad hearing from anyone who run into the same difficulties. What's with bug no. 688 ? Is this really an software bug ? (BTW. a reliable way to reproduce this error could be bonnie). Should I buy another motherboard ?
