I got another panic with yesterday's kernel.
Fatal trap 12: page fault while in kernel mode

fault virtual address = 0xc9256040
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01ccf1b
stack pointer = 0x10:0xf12bb828
frame pointer = 0x10:0xf12bb834
code segment = base 0x0, limit 0xfffff, type 0x1b
