Had been running 3.x series fine for a couple years. >Description: After installing 4.2-RELEASE, the internal hard disk made disk spin-up and spin-down kinds of noises when accessing files. It didn't do this with 3.4 which I had been running. I tried 4.1-RELEASE and had the same problem. So I tried 3.5-RELEASE and the problem went away. Something with the 4.x series. The spin up/down noise sounds like what it does when APM tells it to spin- down. It make the system *VERY* slow. Doing a "config" on GENERIC kernel takes many many times as long as it used to. Oddly, doing something like "ls -lR /etc" doesn't seem to be impacted -- I'm guessing it's the way 4.x accesses the disks. The machine is basically unusable with 4.x, and I wanted to upgrade from 3.x to get access to my PCMCIA SCSI card. >How-To-Repeat: Install 4.x RELEASE from kern/mfsroot floppies, then install OS via FTP from primary site. Reboot. You can hear this first when the OS install is doing the "making the devices" portion of the install. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
