Indeed, compiling in APIC and IO-APIC hides the problem and lets the computer boot and work. By the way, why should people use APIC and IO-APIC on UP computers ? Is it faster or more efficient in some way ? Kernel documentation says that the APIC is a ``replacement for PC-style interrupt controller''. Is there anything the APIC can do that the traditionnal interupt controller can't do ? Kernel documentation is not very incentive for wasting an extra 7.5 ko in the kernel image... >=20 > you have the time, please, attach your "dmidecode" and "acpidmp" to the > bug report at the above URL. >=20 I don't have any dmi and the output of acpidmp is now on the web page given in my bug report. =C9ric ------------------------------------------------------- This SF.net email is sponsored by: VM Ware With VMware you can run multiple operating systems on a single machine.
