Steve!
I compiled new code from bk tree and enabled new cifs code. I mounted
share from w2k server. I was unable to list files. When I chdir to one
known directory I got dmesg full of messages (see below) until system run
out of memory (few seconds - depends on ram and swap). Extended attributes
and Posix layer are not included in kernel - happens same if they are
enabled. Kernel can't kill processes so system freeze.
