On my x86-64 laptop (Targa Visionary 811: Athlon64 + VIA chipset,
Arima OEM:d HW also sold by eMachines and others), ACPI is broken
and hangs the x86-64 2.6.13-rc3 kernel.
During boot, ACPI reduces the screen's brightness (it's always
done this in the x86-64 kernels but not the i386 ones), so I
have to press a specific key combination (Fn+F8) to increase the
brightness. This worked up to and including the 2.6.13-rc2 kernel,
but with 2.6.13-rc3 it causes an error message:
acpi_ec-0217 [04] acpi_ec_leave_burst_mo: ------->status fail
on the console, and then the machine is hung hard.
With the i386 kernel, both this key combination and the other one
for reducing the brightness work as expected.
A diff between the dmesg logs for 2.6.13-rc2 and -rc3 (included below)
indicates that APCI experiences several new errors in rc3.
