Kernel 2.6.6 panics when config'd for my P4 but not when config'd as i686
I have a new Dell P4 HT on which I've been running Fedora Core 2 and everything's been great. But the FC2 kernel is configured for an i686, so when it was time for me to build my own kernel (2.6.6), I configured it for my P4.
The result: kernel panics during boot (at varying points in the boot sequence, usually during or just after networking config).
I tweaked everything I could think of and rebuilt the kernel probably ten or fifteen times, but still got kernel panics every time. Finally I gave up on the P4 configuration and backed off to i686 -- and now it works great.
What gives? Thanks in advance for any help.
