Me again. ;-) Checking my old logs further, I found 92 incidents of "BUG: soft lockup" from a variety of processes (kswapd, soffice.bin, mythbackend, firefox-bin, soffice.bin). In each case, the CPU (sometimes CPU#0, sometimes CPU#1... I only have two cores) is stuck for a reported 61s.
Googling "lucid BUG soft lockup 61s" reveals 100's of threads and dozens of related bug reports... not just ubuntu, either. Some suggesting it's KMS related, and that "nomodeset" in the kernel boot options is a possible work around. Will give it a try and report back.
