The above mentioned email (subject "PANIC with tonight's -CURRENT") has
the DDB trace (though it might not be very useful), and my machine is:
CPU: Intel Pentium III (748.28-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x683 Stepping = 3
Features=0x387f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,PN,MXX,FXSR,SSE>
640 MB RAM
FreeBSD 5.1-CURRENT #11: Sat Oct 11 01:26:41 EDT 2003
