I am seeing a problem on my Dell Inspiron 1520 laptop causing a boot failure (hang) after r199067 with -CURRENT. Kernel with 199066 works fine. System is amd64 running generic kernel, and no loader.conf entries. System has latest bios update. CPU: Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz (2194.52-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x6fa Stepping = 10 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0xe3bd<SSE3,DTES64,MON,DS_CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM> AMD Features=0x20100800<SYSCALL,NX,LM> AMD Features2=0x1<LAHF> TSC: P-state invariant real memory = 2147483648 (2048 MB) avail memory = 2052681728 (1957 MB) ACPI APIC Table: <DELL M08 > FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs FreeBSD/SMP: 1 package(s) x 2 core(s) cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 Root FS happens to be on USB (although looking at the svn diff for 199067, I am guessing this does not make a difference) Hang occurs right about the time that I would expect to normally see the following: SMP: AP CPU #1 Launched! This is a hard hang requiring 4 second power button push. Please let me know if any additional details or tests would be useful. ---Dave Horn
