I've been having the same problem both with 2.6.7 and 2.6.8 images
(always with 686 smp).
The problem is directly related to acpi and I was using the parameter
"acpi=off" at boot time to solve it. Today, I recompiled the kernel,
changing as follows:
--- /boot/config-2.6.8-1-686-smp 2004-08-28 13:48:08.000000000 -0300
+++ .config 2004-09-26 02:25:08.000000000 -0300

CONFIG_ACPI_BUS=y
CONFIG_ACPI_EC=y
This solved the problem. The rest of the config file is exactly the same, but
by changing this, I could boot normally without the "acpi=off" parameter.
I'm not sure if it's all or just some of the options that made the real
difference.
This is being tested in an Intel Pentium IV, with Intel Motherboard D865GBF.
I'm attaching my cat /proc/cpuinfo and my lspci just in case you want to know
the exact details of the box.
I can provide extra information if needed.
I hope this helps in fixing the bug.
