Hi, thanks for taking a gander at my problem. The original panic can be reviewed here: http://article.gmane.org/gmane.os.freebsd.current/31913 now to answer your query...

(kldstat shows no modules, just 'kernel'). In fact I only downloaded the 'kernel' file for each snapshot off current.freebsd.org, placed it in it's own directory under /boot and referenced it explicitly at the boot prompt. Beginning at the oct 17th snapshot, I got the same panic as referenced in my original post to the list. Does anyone else have a box with several legacy isa pnp cards or embedded devices that can try to boot up -current from after the 17th? -- othermark atkin901 at nospam dot yahoo dot com (!wired)?(coffee++):(wired);
