Well, it's PLIP panic time.
I've already had several total machine lockups (while using X) during
ftp's between a P100, running 2.1.0-Release, and a DX4-120, running -current
as of 27/5.
Here's the layout:
+------+ +----------+ +-------+
|laptop| | DX4-120 | |ftp'ed |
| P100 +-----plip----+ with arp +======ne2000 ethernet====|machine|
+------+ | + IP forwarding +-------+
+----------+ ^
| |
+---------------------------> direct ftp to this machine --+
I finally got hold of the panic page:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xf08b4b6d
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf018a641
stack pointer = 0x10:0xf01accf4
frame pointer = 0x10:0xf01acdc0
^^^^ :-)
code segment = base 0x0 limit 0xFFFF, type 0x1b
= DPL 0, pres 1, def 321, gran 1
proc flags = interrupt enabled, resume, IOPL=0
current process = Idle
interrupt mask = net tty
panic: page fault
nm /kernel | sort | grep f018a gives me:
f018a334 t _ed_ioctl
f018a51c t _ed_get_packet
f018a79c t _ed_pio_readmem
f018a854 t _ed_pio_writemem
f018a950 t _ed_pio_write_mbufs
f018ab48 t _ed_setrcr
f018ac4c t _ds_crc
f018aca8 t _ds_getmcaf
f018ad30 F isa.o
f018ad70 t _conflict
f018adec t _haveseen
f018af04 T _haveseen_isadev
I am now going to try a DIRECT ftp over plip (no forwarding)
between the DX4 and the P100, and see if it still occurs (no
ed0 interaction).
