Dear sirs,
I am a telecommunications engineering student from Barcelona, and I
have the following problem (and hope that maybe you could help me).
I have added some new code to the TCP/IP stack of a FreeBSD 3.2, and
now I'm trying to create a new kernel which would include the upgrades
added.
I follow the "config, make depend, make, make install" sequence as
specified in Chapter 7 in your freebsd.org handbook, and everything
seems to turn out right.
Now, the problem is that, after the reboot phase (and entering "login"
& "password"), the new kernel seems to work right (i.e., for a while,
all the commands work ("ls", "ping", "ftp", "ps", etc)), but after one
or two minutes, it hangs. Then, the following message appears on my
screen:
_____________________________________________________________________________
panic: m_copym
syncing disks...
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xb8
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01625cf
stack pointer = 0x10:0xc02cf060
frame pointer = 0x10:0xc02cf060
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL0, pres 1, def32 1, gran 1
processor flags = interrupt enabled, resume, IOPL = 0
current process = Idle
interrupt mask = bio
trap number = 12
panic: page fault
Automatic reboot in 15 seconds... press a key on the console to abort
_______________________________________________________________________________
Do you have any idea about which could be the problem or how could I
solve it?
Thank you very much,

PD: previous to this process, I built a new kernel (without any upgrade,
just to test the bulding sequence) and everything worked, so I think
it's me who's the reason of the problem...
