Time to burn a 5.2.1 CD? Ouch. I'm having trouble figuring out why the old kernel won't boot. As Kris said someone has suggested this is similar to the problem we had with make_dev() on the Alphas. That's certainly possible but if that kernel had been running before I'm not so sure that's the problem, I don't understand how the kernel would have been able to run before if it's really the make_dev() issue. You might want to give the ISO in snapshots/sparc64 on the mirror sites a try instead of the 5.2.1 CD, especially if you had already made the leap to 64-bit time_t. I was in the process of trying to create a newer version of that when I came across the problem with the root drive not being mountable. Now that it's fixed I'm trying again but it will be a day or so before that's ready (if all goes well this time :-). Can you let us know what hardware you have? I'm most interested in general model (e.g. Ultra-30?) and whether it has a graphical console that's supposed to work (e.g. Creator-3D?). If it does have the graphical console as a last resort you could try detaching the keyboard and connecting a serial console to see if you can coax it into booting the older kernel that way. I haven't been having problems with serial console machines at all recently...
