[Bug 52553] Re: Kernel panic - not syncing: IO-APIC + timer doesn't work!

[Rob van den Bogaard]

Also see bug #54621 for linux-source-2.6.17 (Ubuntu)
(which is in turn marked as duplicate of bug #53985)

Today I stumbled upon a possible quickfix (didn't try it myself yet, I'm happy enough I got lilo booting again after a kernel update, but that's a different story). It's found at:
www.xs4all.nl/~hajk/mbook-install.pdf

It adds a parameter to the lilo.conf "Append" value:
append="quiet splash lpj=8000000"

Excerpt:
"The boot option lpj=8000000 (eight million) fixes the kernel panics frequently occurring when booting the current Ubuntu kernels (including those in Edgy), see bug #54621 in Launchpad/Malone. This option is quite harmless and sets BogoMips (an approximate speed measure) for the 1.83GHz Core Duo T2400 processor in the MacBook to a reasonable value (about twice the average BogoMips per core followed by three zeros), rather than rely on a kernel estimate during booting (see the output from dmesg) that may be wildly off. Users with a 2.0GHz processor should use a value that’s 10-20% higher, the exact value isn’t that important."
