I am trying to upgrade a karmic system to lucid. I had it working in the past, but on or about Jan 8th, an upgrade to lucid killed the system. It would no longer boot, freezing after the udev warnings in the boot process. I have re-done the upgrade several times since then, and it always fails at the same point. There are a few errors during the upgrade, requiring --force-overwrites, but in the end, everything seems to go through properly. No logs are being written to the system, suggesting that the file system is not being mounted. I tried the upgrade again last night, and ran update-initramfs after the upgrade just to make sure it worked, and it ran without errors.
I am not sure exactly what is failing, maybe mountall, but since there is no log file being written, it's pretty hard to trace. Any ideas on this?
Note: I can access the file system from karmic, so that much is intact.
Edit: I should mention that this is actually kubuntu, on a 64-bit quad core system.
