Any thoughts? And this one comes up with the recent update too: driver bug: Unable to set devclass (class: acpi_sysresource devname: (unknown)) driver bug: Unable to set devclass (class: acpi_timer devname: (unknown)) cpu0: on acpi0 driver bug: Unable to set devclass (class: acpi_sysresource devname: (unknown)) cpu1: on acpi0 driver bug: Unable to set devclass (class: acpi_sysresource devname: (unknown)) cpu2: on acpi0 driver bug: Unable to set devclass (class: acpi_sysresource devname: (unknown)) cpu3: on acpi0 What the additional info should I supply to understand what's wrong? Here is my full dmesg; http://people.freebsd.org/~rm/dmesg.txt -- Regards, Ruslan Tinderboxing kills... the drives.
