Hi Tommy and sorry for dropping the ball on this, I didn't remember this
mail anymore until I look for more reporters of the inode related
problems.

Current mainline (Linus' git as of today) has a lot of the fixes in this
area, any chance I could trick you into trying it?  Maybe including the
debug patch below which adds a printk to that one culprit that I thing
might remain:

Also if it still happens any chance you could send output of the dmesg
command instead of the syslog files?  For some reason syslogd usually
eats up some bits of kernel oops message..
