Init_dev never touches tty_sem. In which case, I have to say... Congratulations! You've found a bug with Red Hat's Enterprise Linux kernel! Go straight to Red Hat's bugzilla! Do not collect 200$.

Mainline kernels appear to work properly. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core
