The latest GCC in Fedora rawhide contains some serious bug (or provokes a 
latent one in the kernel) that makes every kernel built unbootable. It just 
locks up halfway through the init. Kernels that previously worked fine all now 
experience the same symptom. Even RH's own kernels exhibit this. The kernel 
built Nov 24th works, Nov 26th doesn't. gcc was updated 26th, 14 hours earlier.


Digging a bit further, it is indeed the high-res stuff (the first missing 
message) that hangs. If I hard code the kernel to just be non-high-res capable, 
it boots, but time keeping is horribly broken.

Anyway, hopefully this means I'll soon have the object file that gets 
miscompiled. Jakub also pointed me to an older gcc RPM so that I can produce an 
object file with that as well and see what differs.

If you are referring to the "compat" RPMs, be aware that they use the current headers, which is a good or bad thing depending on what you want to do. If you want to build old software, you get to keep a down-rev virtual machine to do it right :-(
