Hi all,

Using 2.6.14-rc5-mm1 with the spinlock inlining patches reversed and a couple of reiser4 patches from namesys.com. I mounted 3 CDs in succession (different ones, but same supplier) and the kernel spewed these messages out for each of the CDs:

Everything seemed to work just fine mind you, just scary messages. :-)
