Just wanted to follow up here - I'm now using Lucid, and haven't had this specific problem. I have had a lot of random system lockups and other errors. It seems for the moment, however, that setting the DRAM clock to 166MHz (rather than 200MHz as reported by the SPD) has fixed them.
I believe that my particular chipset/motherboard/cpu combo has some hardware bug in it, which from the sounds of it may be pretty common. -- BUG: soft lockup - CPU#1 stuck for 61s!
