I've gut got these messages:
Warning: bad magic number for tty struct (04:41) in release_dev
rs_close: bad serial port count; tty->count is 1, state->count is 2
It happened when I stopped PPP connection. What's going on out there ?
I've been looking, and I think I've found a bug in the release_dev()
code. Here's a patch versus the 2.0 kernel; a similar patch should be
made to the 2.1 kernel. Can folks who have had this problem in the past
try testing this patch and letting me know if it fixes the problem?
Thanks!!
