ncplogin panic

[m.ehinger at ltur.de]

Hi,

i had the same problem. See my thread on the freebsd-fs mailinglist

http://lists.freebsd.org/pipermail/freebsd-fs/2006-July/002060.html


After some research i use the attached patch against ncp_sock.c.

So it is not the real solution to this problem it only avoids the panics. I'm using it quiet a while without any other known
problems.
Hopefully someone with more knowledge can help on this.

I also get some "md_get_mem(461): incomplete copy" messages which seem to do no harm, so far.

Regards,

Maik
