Description fukuhara 2000-02-26 20:10:01 UTC

I use diskless PC and kernel with BOOTP support.
IP address is set by DHCP, but if I execute
(of cource this is nonsense)
dhcpclient fxp0

result is
Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x3e
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc01ed0cc
stack pointer           = 0x10:0xc5eadbc0
frame pointer           = 0x10:0xc5eadba4
code segment            = base rx0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL=0
current process         = 205 (sh)
interrupt mask          = net bio cam
trap number             = 12
