Same problem here after upgrade:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x20:0x0
stack pointer = 0x28:0xd4af1cc4
frame pointer = 0x28:0xd4af1cdc
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 25 (irq18: em0 atapci2)
[thread pid 25 tid 100019 ]
