Fedora's latest gcc produces unbootable kernels

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.

The last message printed is:

isapnp: Scanning for PnP cards...

Comparing with the working kernel, the next steps are:

isapnp: Scanning for PnP cards...
Switched to high resolution mode on CPU 0
isapnp: No Plug & Play device found

Any ideas on how I can work around this? I'm rather unproductive when I can't build working kernels.. :/
