When drive dies or when it's removed from the server the system freezes on disk operations, until reboot or until same (or new) drive is inserted. After that the system runs normally. This is reproduceable and I encountered this on i386/amd64. This cannot be helped by upgrading the controller firmware (I downloaded and upgraded to the latest available from IBM support site). ps in debugger shows a great amount of processes in D state. >How-To-Repeat: Get an IBM System X server. Install FreeBSD onto a geom_mirror or zfs mirrored pool. Pull out one drive. Issue some disk i/o related command. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
