Hi,
panic: Most recently used by routetbl
I get this type of panic withing minutes of uptime with a -current of
25-Jun-2002 around 13:52 GMT-2. Another anomaly is that name resolution
doesn't seem to work reliably, or maybe even TCP in general has a
problem -- it all takes very long if it works at all.
This is still a pre-KSE-III system.
As a workaround I am currently running with a kernel of about 11 Apr in
the same userland, which seems to work.
