Dear Sir/Madam:

I'm using a two 1GHz Pentium III processors computer
with an ASUS CUV4X-D motherboard.  When trying to
boot with the 2.4 kernel of the RedHat 7.2 distribution,
I find the warning:

WARNING:  unexpected IO-APIC

Short afterwards, the system hungs.  The last message is

"checking TSC synchronization accross CPUS"

The system boots normally with the 2.4 kernel without SMP and
with the 2.2 SMP kernel of RedHat 7.0.


Any suggestion?.


Best
