On the console a lot messages similar to: [..] mpt0: Request 0xffffffff89b966d8 Timed out. mpt0: Request 0xffffffff89b962e8 Timed out. mpt0: Request 0xffffffff89b974a0 Timed out. mpt0: Request 0xffffffff89b960a8 Timed out. mpt0: Request 0xffffffff89b96d08 Timed out. mpt0: Request 0xffffffff89b96de0 Timed out. mpt0: Timedout requests already complete. Interrupts may not be functioning. [..] The hardware is Sun V20z (Dual Opteron Machine) running FreeBSD 6.0/amd64 using a SMP GENERIC kernel (save different ident). I have geom-mirror enabled on the box. The problem appeared only after the geom-mirror was created. Currently I cannot access the machine, because over the holidays no one is there to reset it. :) I will enable kernel-debugging features when I have access agin. >How-To-Repeat: n/a >Fix: n/a >Release-Note: >Audit-Trail: >Unformatted:
