With very recent kernel I have a panic once per several hours, always in swi1:net, always something called from tcp_sack_option (), see example below: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x4 fault code = supervisor read, page not present instruction pointer = 0x20:0xc0539f12 stack pointer = 0x28:0xcc7e4a8c frame pointer = 0x28:0xcc7e4adc 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 = 29 (swi1: net) trap number = 12 panic: page fault #5 0xc05ccea0 in trap () #6 0xc05bdf0a in calltrap () #7 0xcc7e0008 in ??
