bizzare..
the story is rather long but there may be people interested
i still don't know why this happens, and i wish there is an easy answer.
Cheers,
Panos
Background
this appeared sometime ago in this list under ("Re: network problem") and was
about a problem with an ethernet interface (ed0) which was 'going to sleep'
and connections freezed, pings stopped etc. and when i kick it (send/tcpdump)
everything resumes till the next time (soon)
Fix
it appeared not to be a H/w problem after all
..what fixed was just compiling a kernel locally.
i brought the src-sys and rebuilt the kernel _locally_ and now it is working
fine (the _same_ kernel config file!)
Story
the "problematic" kernel had "past" which
appeared in freebsd-questions ("Re: mounting sources and building kernels") a
couple of weeks ago (in brief: i was compiling on a 'server' machine which
had the sources then mounting /usr/src on the machine which had the problem
and did 'make install' )
this is how i bult the kernel that was causing the problem:
---------------------------------------------------------------
is it possible to have all sources in only one "server" machine and use it to
upgrade another "remote" by letting the "remote" mount the "server"?
(i NFS export /usr/src -maproot=root on the server)
i have upgraded the system from 2.2.6 -> 2.2.7 by 'makebuildworld' once on the
server and then
on the "remote" :
mount server:/usr/src /usr/src
cd /usr/src
make installworld
that seemed to have worked...
i have difficulty with building a kernel like this though,
on the "remote"!!:
mount server:/usr/src /usr/src
cd /usr/src/sys/i386/conf
/usr/sbin/config REMOTE-KERNEL
cd ../../compile/REMOTE-KERNEL
make depend
make ... ...
Error 1 at vnode_if.c (first file to cc)
in fact i receive several 'warnings' at vnode_if.c all like this :
vnode_if.c:640: warning: excess elements in struct initializerafter
`vop_vfree_desc`
*** Error code 1
if i build the kernel on the "server"
and on the "remote" just 'mount' 'cd' in the REMOTE-KERNEL compile directory
do 'make install' then it does not complain.
BUT THIS KERNEL had the ed0 sideffect.
i'd be very interested to know why this happens?
