Bug 34405

FreeBSD-CURRENT seems to have minor issues booting on a machine previously placed in hibernation by windows 2000. When booting from an apm suspend command (apm -z, or zzz), this is not an issue.

sample from the dmesg:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x4
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc0240dca
stack pointer           = 0x10:0xc05aeb04
frame pointer           = 0x10:0xc05aeb10
code segment            = base rx0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 0 (swapper)

Fix: 

no idea. i'm still trying to get a decent trace and dump of the information. More to come, promise.
How-To-Repeat: So far, i've only seen this on a Toshiba Satellite Pro 4600:

First, boot in to windows 2000, place the machine in to hibernation mode.

then boot to FreeBSD, and watch the fun begin:
