System hangs during boot in SMP mode

Bug #58752 reported by Giblet5 on 2006-09-03
Affects Status Importance Assigned to Milestone
linux-source-2.6.15 (Ubuntu)

Bug Description

The symptom is that the boot process hangs and the keyboard is frozen.

HW: MSI 945p NEO/Platinum M/B
    Intel Pentium D 920 (EMT64, dual core, C1E bios supported)
    2 * 1024MB DDR667

On installing 6.0.6-1 (standard 386 kernel) everything works very well (for 386-UP).
I then use synaptic to download/install the 2.6.15-26-686 SMP+UP kernel.

It boots OK but hangs the instant the boot has completed.

BUT if, in the BIOS, I turn OFF APIC, it boots fine. I have tried both APIC on with
mps level 1.1 and 1.4, but both hang.

This is very similar to the problem reported by 'Zoltan' in 9357. He never opened a bug report - he bought a new motherboard and CPU!

Thanks in advance,
