Well, it is still mounting after ~16 hours, and > I got messages like these at first: I recommend trying a 3.14 kernel. I had ongoing problems with kernels before 3.14 which included infinite loops in kernel space. Based on reports on this list I haven't been inclined to test 3.15 kernels. But 3.14 has been working well for me on many systems. Trying 3.14 can't hurt. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
