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....
