Hi Dave!
That's ... unexpected. That implies that ip->i_temp == NULL after it
has been joined to a transaction. I can't see how that could occur
there.  Can you recompile the kernel with CONFIG_XFS_DEBUG and
re-run the test as that option includes all sorts of sanity checks
for ip->i_temp?
CONFIG_XFS_DEBUG is enabled now. Is there anything special in dmesg i should look for? Or should i just send another oops when it happens again?

thanks,
Michael
