This "different crash" I mentioned appears to be related to the netconsole I was using (serial console produces stairstepping text, netconsole seems to duplicate lines--go figure). Without netconsole, dynamic tick appears to be working, so I'm not sure whether this is a netconsole bug or a dynamic tick bug. While dynamic tick no longer panics, with dynamic tick, my system slows to whatever is slower than a crawl. It now takes 6 minutes 50 seconds to boot all the way up, compared to 1 minute 35 seconds with my 2.6.12 kernel without the dynamic tick patch. I'm not sure where this slowdown is occurring yet.
