Hi All,

I'm experiencing some soft lockup problem on fedora core 5 v2.6.19-1.2288.fc5 x86_64
with a dual HT Xeon 3.2GHz EMT in ASUS NCT-D mobo. This problem still happening
everytime I switch on the box, but disappear if I reboot the box by a Ctrl-Alt-Canc just after
the BIOS startup and without booting the kernel. The box stay up without any problem so far. 
Furthermore booting with noapic the box doesn't show any problem.
The bios on the motherboard has been already updated to the last available.

Does anyone have some tips to suggest?
