Fatal trap on CURRENT

Hi!

I have CURRENT from Mar 30. And I've got a trap (see below). Something 
wrong with TCP?

Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 06
fault virtual address   = 0xc
fault code              = supervisor read, page not present
instruction pointer     = 0x20:0xc0517f6e
stack pointer           = 0x28:0xe4f08924
frame pointer           = 0x28:0xe4f0892c

                         = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 22 (em0 taskq)
trap number             = 12
