Hi,

I've been seeing this for a while now, but its still present with -rc5+
kernels. Its always the local machine failing, never the remotes.

[root@twins linux-2.6-rt]# nice ./k opteron build
time distmake x86_64 O=opteron-build ARCH=x86_64
testing twins:    distccd running
testing opteron:  DOWN
testing taijtu:   distccd running
testing dyad:     distccd running
testing lappy:    host running
testing ubuntu:   host running
DISTCC_HOSTS= twins/8 taijtu/32 dyad/32
DISTCC_DIR=/dev/shm/distcc
DISTCC_SLOTS=72

...

distcc is very good at breaking networking.  I assume 2.6.26 is OK?

I think it was - whew .26 was a long time ago already ;-)

I'll build and boot one today to confirm.

It seems I can reproduce similar errors with .26 - I'll be traveling
soon and this box is one of those without serial console so It'll have
to wait until I get back.
