    No. 2.6.32.5 (the one that currently ships with Debian stable).

    This is a tower I built up several years ago, mostly as a sandbox - some
    aftermarket motherboard,
    don't have the paperwork anymore, and I'd have to pull the machine apart
    to get details off the
    board itself. Phoenix BIOS, somewhat old.

    Since this thing sits under my desk, with the reset button close at
    hand, this is more a curiosity
    question - not as if this was one of our production servers sitting in a
    remote datacenter (those
    reboot just fine). An itch that wants to be scratched, an opportunity
    to learn a little about obsolete
    hardware, but not something really meriting in-depth attention.

    Still....
