I am seeing a problem on my Dell Inspiron 1520 laptop causing a boot
failure (hang) after r199067 with -CURRENT. Kernel with 199066 works
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
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
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.
