"Hi, This seems to be te cause of the “APIC kernel panics”:
http://llistes.bulma.net/pipermail/bulmailing/Week-of- Mon-20060703/077657.html (it’s in spanish) According to the above link, recompiling the kernel to use a timing frequency of 1000 Hz instead of the 250 Hz solves the “panic” problem. You can install the “linux-source-2.6.15″ package and follow the instructions here to build the kernel: http://ubuntuforums.org/archive/index.php/t-24853.html (Note that you have to add a “–initrd” switch in the “make-kpkg” command to make it generate an “initd.img” and make the kernel boot properly) The problem is that the restricted modules won`t be installed with this new kernel, and this includes the “madwifi” driver for the wifi… So you have to add it. Greetings, Marco. " This is a comment on the site: http://bin-false.org/?p=17 If you search the page for "APIC," many many people are having this problem?
