Real-time kernels from the Ubuntu Studio Lucid repositories

[Mike Holstein]

that is totally interesting... i have about 4 machines that boot the -rt
kernel, and the -realtime kernel without issue... also, a 64bit install with
the same results... i cant help much with the self builds, but go ahead and
spit out some more logs here, and lets try and figure out why your not able
to boot...
