I just noticed: Doing a simple "cat /proc/$$/map" panics the system:

kernel trap 12 with interrupts disabled

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x0
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc01f9ec3
stack pointer           = 0x10:0xc6eefccc
frame pointer           = 0x10:0xc6eefcd8

                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = resume, IOPL = 0
current process         = 35 (cat)

Is it just my setup or a general problem? If it happens only on my
system I can give further details.
