That's just fine. Any bugs in that have been squashed in the
last few revs.

You should select this. (CONFIG_DEVFS_TTY_COMPAT) as yes.
At least I do, and it works for me.

I have this set to y (CONFIG_DEVFS_BOOT_OPTIONS)

So try the CONFIG_DEVFS_TTY_COMPAT=y, and lemme (or Gooch) know.
I was doing massive compiles in X last night, two to four different
compiles at a time, ie two versions of pgcc, lesstif, lotsa stuff
and many xterms AND vc's open. Never had an oops.

However, I KNOW Richard would be interested in hearing exactly
what is causing an oops, and at what point.

Do some straces, test a non-patched kernel, etc...
