What does "too many hoops" mean in this context? I had clicked through a couple of "click here to download picture" screens (each trying to push a pop-up) before I decided it looked too much like malware. >>> The system boots fine single-user, so I don't suspect the base >>> kernel functionality. >> >> Maybe. >> >> What you should do is install the kernel *before* the userland.

Also, minimize the software started at bootup in order to reduce the number of variables. If it's still crashing at that point, go to the Handbook (or maybe it's the Developers' Handbook?) for instructions on diagnosing crashes. If not, then re-enable the userland stuff gradually to find the culprit. It also may be useful to look at the -STABLE mailing list, as at least one crash problem has been solved recently. Good luck.
