PCBSD 8.1-RC1 Kernel Panic on Reboot.<br>
<br>
=========================================================<br>
There is a kernel panic on boot up shortly after the PCBSD Welcome
Screen and immediately after the ZFS Server Pool version message and
the Timecounter frequency and Tick counter reports:<br>
<br>
Fatal trap 12: page fault while in kernel mode<br>
cpuid = 0; apic id = 00<br>
fault virtual address = 0x797469<br>
fault code = supervisor read, page not present<br>
instruction pointer = 0x20:0xc1ab1a41<br>
stack pointer = 0x28:0xc1c20bec<br>
frame pointer = 0x28:0xc1c20bec<br>
code segment = base 0x0, limit 0xfffff, type 0x1b<br>
= DPL 0, pres 1, def32 1, gran 1<br>
processor eflags = interrupt enabled, resume IOPL = 0<br>
current process = 0 (swapper)<br>
tran number = 12<br>
<br>
panic: page fault<br>
cpuid = 0<br>
Uptime: 1s<br>
<br>
Cannot dump. Device not defined or unavailable<br>
<br>
Automatic reboot in 15 seconds . . . etc, etc.<br>
<br>
<br>
<br>
Comments:<br>
<br>
1. This computer was the subject of a previous report about the
upgrade freezing followed by spontaneous reboot. (Kris -- You will
remember telling me afterward not to do a fresh install after a kernel
panic.)<br>
<br>
2. I did a "fresh install" and it has worked fine for several days.<br>
<br>
3. Immediately before the kernel panic, the last thing I did was
install the Virtualbox PBI and rebooted. The shutdown portion of the
reboot was normal and without incident.<br>
<br>
4. The kernel panic is repeatable 100% of the time.<br>
<br>
5. Toggling ACPI off makes no difference.<br>
<br>
6. Nor will it start in the safe mode. <br>

Gotcha, this is a problem with the VirtualBox application. The
vboxnetflt module causes a kernel panic at boot on 8.x. I've reported
this to the developers already and am working on a fixed PBI now for
the final ISO / pbidir. <br>
