Today I've encountered the following kernel panic with openafs 1.4.0 on

That's a bit difficult to tell before we know why it broke.
I have not seen this particular bug before, someone else
might.
Let me see... We are in afs_NewVCache() and call osi_Panic().
Unfortunately osi_Panic() did not write the message string,
but only called BUG(). (Can we fix that for the future?)
There's nothing to fix. osi_Panic _does_ print out the message string, but
necessarily does so _before_ it calls BUG(). Which means that users
habitually don't actually copy the message when sending in a report.
Fixing this would require changes to Linux to allow something calling BUG
to include a message that gets included _below_ the "cut here" line.
Normally afs_NewVCache() works, so why did it not work for
you here?
So the standard questions are:
... all the ones you mentioned, plus "what were the last few messages right
_before_ the 'cut here' line.
Also, the standard cause of NewVCache failing in 1.4.0 on a Linux 2.6
system is that the default parameters include only 300 vcache entries,
which is nowhere near enough.
