If accessing a powered down hard drive does not cause a lockup, then messages such as the following are reported: kernel: ad1: TIMEOUT - READ_DMA retrying (2 retries left) LBA=32547130 >From my websearching, it seems the IDE subsystem in the 5.x branch is the problem and 4.x and 6.x lack the issues I'm reporting. I was hoping that 5.5 would contain the patch that Søren Schmidt released (ATA-mkIII), but apparently that is not the case. Note that I'm only writting this bug report because the server has rebooted 4 times today, and WindowsXP is starting to look much much more stable than FreeBSD. >How-To-Repeat: >Fix: If one turns off powering down of hard disk drives, this would obviously solve the problem. The patch by Søren Schmidt may or may not also work. Migrating to 6.x should also work. >Release-Note: >Audit-Trail: >Unformatted:
