Perhaps this will stir some other committers' thoughts/memories.
Ok here we go...
Regression report (GENERIC kernel):
1) 2004.02.06.00.00.00 - works
2) 2004.02.08.00.00.00 - works
3) 2004.02.10.00.00.00 - buildkernel failure
4) 2004.02.10.12.00.00 - panic
5) 2004.02.09.12.00.00 - works
6) 2004.02.10.06.00.00 - works
So...something committed (and which still exists) between 2004.02.10.06.00.00
and 2004.02.10.12.00.00 results in the following sort of early panic.
