for a long time, and on different hardware, writing to a local disk
with data from the net (tar/dump etc) panics.

this one in particular, is quiet consistant:
tar cf - -C /net/.... | tar xvpf -

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0xc0f7
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc05a1430
stack pointer           = 0x10:0xc655d7e0
frame pointer           = 0x10:0xc655d8bc
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         = 494 (tar)
kernel: type 12 trap, code=0
Stopped at      ip_output+0xe10:        leal    0xffffffd4(%ebp),%eax

any help I can provide?
