2.4.18-rcx: Dual P3 + VIA + APIC

[Adam Lackorzynski <adam@os.inf.tu-dresden.de>]

Hi,

trying to boot a 2.4.18-rc1, 2.4.18-rc2-ac1 or 2.5.5pre1 on a dual P3
with a VIA chipset hangs (randomly) at the "=====" signs, sometimes the
screen is flickering:

CPU: L1 I cache: 16K, L1 D cache: 16K
CPU: L2 cache: 256K
Intel machine check reporting enabled on CPU#0.
CPU0: Intel Pentium III (Coppermine) stepping 06

or it hangs after initialising the SCSI driver (sym), IDE, network etc.
seems ok:

...
sym0: SCSI BUS has been reset.
scsi0 : sym-2.1.17a

It never went further.


Booting with "noapic" works, as do UP 2.4 kernels and 2.2.20 SMP
kernels.
