OK, that looks like filesystem corruption of some kind - you have a 
directory entry for inode #344, but the inode itself doesn't exist.

Does it printk any other clues as to why that happened? Nodes with a bad 
CRC, perhaps?

That's very odd. Can you print the return code (and errno) of the unlink() 
syscall? That really ought to work.

Can you compile with CONFIG_JFFS2_FS_DEBUG=1, set /proc/sys/kernel/printk 
to 9 and log the kernel's output during mount and unlink attempts?

I assume the old kernel is showing the same behaviour if you reboot back to 
it?
