Hello,
I am testing the devel kernel 2.5.24, when the kernel boots
up I get a warning about an unknown IO-APIC and the kernel
asks me to email linux-smp@vger.kernel.org
Attached is the complete output from dmesg.
For your info I am running:
mobo: Asus A7V333 with kt333 northbridge and vt8233a southbridge
cpu: Athlon XP 1900+
If there is anything else I can do to help out, let me know.
Thanks,
Mike Closson
